Description

[0001] “CONTAINER FOR GROWING RASPBERRY”

[0002] DESCRIPTION

[0003] FIELD OF INVENTION

[0004] The invention concerns a container for floriculture and / or horticulture. Specifically, the invention concerns a container for growing fruit plants, more specifically berry plants, such as raspberry plants.

[0005] BACKGROUND

[0006] Traditionally, raspberry cultivation requires large spaces and specific environmental conditions to ensure adequate root development and proper nutrient distribution.

[0007] The present invention relates to an innovative container for the professional cultivation of berries, such as raspberries, designed to optimize the growth and productivity of plants in controlled environments, as well as in small spaces, such as terraces or greenhouses.

[0008] Growing raspberries can be very profitable, but it presents several challenges that are important to manage to achieve good harvests.

[0009] To ensure good raspberry production, it is essential to consider a series of factors related to crop management, including soil, container characteristics, and protection of the plant from diseases and parasites that can be detrimental to its health and the quality of the fruit it produces.

[0010] Raspberries, in fact, are extremely delicate plants, exposed to the development of plant diseases and mycoses linked to contamination by pathogens present in the soil beneath the container containing the plant, which can rise up into the substrate through the drainage holes in the base of the container and attack the roots. Some pots on the market include thin pedestals designed to create a distance between the base of the pot and the ground below.

[0011] However, these supports consist of thin, discontinuous segments with limited capacity to support the load of the container and its contents. These supports tend to deform or sink into the underlying ground, reducing their ability to provide sufficient structural support to ensure an adequate distance between the base of the container and the supporting surface.

[0012] Another well-known technique for isolating containers from the ground below is to mulch them with black plastic film under the containers. Mulching prevents weed growth by blocking sunlight, thus reducing competition for nutrients and water between cultivated plants and weeds. Similar systems involve the use of polystyrene sheets.

[0013] However, when used in areas with high rainfall, these can lead to high moisture retention, creating an environment conducive to the development of fungal diseases and root rot.

[0014] Furthermore, plastic film tends to deteriorate over time and must therefore be replaced periodically, creating a disposal problem that negatively impacts the environment.

[0015] Known techniques for controlling common diseases that can affect raspberry plants include preventative or curative treatments using copper-based products or organic fungicides.

[0016] An object of the present invention is therefore to provide a container for growing raspberries that, thanks to its geometric characteristics, guarantees the health of the plant and the quality of its fruits, avoiding or reducing the use of additional plastic materials and / or chemical products harmful to the environment.

[0017] Another important factor to consider when growing raspberry plants is the type of substrate in which the plant grows. To ensure optimal growth of the plant and the resulting abundant production of tasty fruits, the soil must be kept constantly moist.

[0018] Raspberries therefore require regular watering, but, at the same time, excess water can cause various problems for the growth and health of the plant.

[0019] High humidity can, in fact, cause rotting of the roots and / or fruits.

[0020] Waterlogging is also dangerous for the health of the plant as it can encourage the formation of pathogens and parasites that, by attacking the roots, compromise their health.

[0021] Excessive soil moisture can also promote the onset of fungal diseases, such as botrytis (grey mould), a very common disease in raspberries that can affect fruit, flowers and shoots.

[0022] Waterlogging can also contribute to the formation of fruit with an excessive water content, thereby reducing its flavour and sweetness.

[0023] The ideal substrate for growing raspberry plants must therefore ensure good drainage, rapid flow out of excess water, good aeration and a balanced supply of nutrients.

[0024] The containers for growing raspberries currently on the market have numerous drainage holes in the bottom to ensure that excess water drains away quickly, preventing waterlogging that can damage the roots.

[0025] However, the containers currently in use usually have a flat bottom, which, even if equipped with drainage holes, often causes liquids to stagnate in the lower part of the container.

[0026] In fact, even if present, drainage holes in a flat bottom can be ineffective if the pot is placed directly on a flat surface (such as a saucer or the ground), since the water cannot drain freely. Additionally, in pots with flat bottoms, air has less opportunity to circulate around the roots. Inadequate airflow can lead to oxygen deficiency in the roots, limiting the plant's growth.

[0027] It is well known that to ensure good fruit production, in addition to a good drainage system, good aeration of the soil is also essential, as it ensures healthy growth of the plant's roots within the substrate.

[0028] Another important feature of the container should be its ability to prevent root spiralization; this spiralization causes the plant to suffer, as it is forced to grow within the rigid cord created by the spiralization itself. This has negative effects not only on the plant’s growth but also on its ability to survive and develop properly once repotted or planted in the ground.

[0029] From an industrial perspective, these containers should also be easily stackable on top of each other to simplify both warehouse storage and product handling thus allowing, for example, a reduction in their transport volumes and the associated costs.

[0030] It is clear that designing a container for growing raspberry plants with shapes, geometries, dimensions, and structural characteristics that can simultaneously meet this multitude of requirements is by no means trivial.

[0031] The containers currently on the market attempt to solve drainage problems with holes in the bottom, but they do not effectively address the multitude of issues related to raspberry cultivation mentioned above.

[0032] An object of the present invention is therefore to solve the problems left open by the known technique with a container for growing nursery plants, in particular berry plants and more specifically raspberries, which has a shape that resolves the issues listed above and overcomes any disadvantages of the known solutions.

[0033] SUMMARY OF THE INVENTION The above-described object has been achieved by a container as defined in claim 1.

[0034] The container for growing plants according to the present invention comprises:

[0035] - a base delimited by an edge,

[0036] - a wall extending from said edge of said base, and

[0037] - at least one support extending from said base in a direction opposite to said wall, wherein said at least one support is formed by a continuous outer surface defining a closed support perimeter, and said base includes at least one opening and a depression consisting of a recessed surface delimited by a base perimeter.

[0038] For the purposes of describing the present invention, “recessed surface” shall mean any surface that extends towards the inside of the container.

[0039] The container according to the invention, thanks to its structural characteristics, can be effectively used for growing raspberry plants, plants notoriously difficult to grow, both due to their fragility and susceptibility to the development of plant diseases and mycoses, and due to the particular requirements related to the growth substrate.

[0040] The container according to the invention is characterized by an advanced drainage and aeration system that facilitates plant management while improving water and air circulation within the substrate.

[0041] In particular, the container for growing raspberries according to the invention is equipped with a system for protection against external microorganisms, parasites, and pathogens. This system uses the raising of the base of the container from the underlying soil by means of at least one support extending from the base in a direction opposite to the wall of the container. The at least one support is a closed structural element, i.e., formed by a continuous outer surface that makes it impermeable to water or other fluids. The at least one support has a completely sealed structure, without openings or gaps that could allow communication between the external environment and the substrate. Implementing at least one closed support also ensures greater stability for the pot and avoids the risk of dirt, water or debris accumulating inside.

[0042] Furthermore, the closed structure of the support makes it more robust and resistant, preventing deterioration and at the same time increasing the durability of the container.

[0043] From a practical standpoint, closed supports act as a protective barrier. A closed support helps to keep the pot raised off the ground, facilitating drainage, but without the risk of water or moisture seeping into the structure of the support itself.

[0044] This protective barrier provided by closed supports allows to eliminate, or at least reduce, the use of chemical pesticides, reducing the environmental impact of cultivation and promoting the production of healthier, higher-quality fruit.

[0045] Furthermore, the closed supporting perimeter of the support advantageously distributes the weight of the pot evenly across the entire surface of the support. This helps improve the stability of the pot, especially on smooth or uneven surfaces, reducing the risk of it tilting or tipping.

[0046] The continuous contact of a support with a closed perimeter reduces the pressure concentrated on specific points, protecting any protective sheets placed under the container, and, above all, preventing the container from sinking into the underlying ground. As mentioned above, it is indeed crucial to keep the base of the container at a certain distance from the underlying ground to prevent pests and pathogens from climbing up into the container through the drainage openings found in most plant growing containers.

[0047] The closed perimeter design also provides a larger supporting surface, making the support more suitable for supporting large or heavy pots. The distribution of the load along the entire perimeter helps prevent the support from warping or breaking under pressure.

[0048] A closed perimeter structure generally makes the support more robust and durable than segmented or open supports, offering greater resistance to wear and tear and weathering over time. Finally, the continuous contact of the closed perimeter with the underlying ground can help to better absorb vibrations or small movements, reducing the risk of slipping or unintentional movement of the pot, especially in situations where there are light impacts.

[0049] In one embodiment, the at least one support of the container according to the invention has a height between 2 and 7 cm, preferably between 2.5 and 5 cm.

[0050] In one embodiment, the at least one support, in its support position, engages a support area, the value of which is between 0.5 and 5% of the flat area defined by the edge of the base of the container, preferably between 0.7 and 3%.

[0051] The height and support perimeter of at least one support can vary depending on the shape or size of the container or according to the particular needs of the plant to be grown.

[0052] In one embodiment, the at least one container support according to the invention has a cylindrical or frustoconical shape.

[0053] The at least one container support according to the invention can be fixed to the base of the container by gluing, fusion casting during production, or fastening, depending on the material of the pot itself. Alternatively, it can be an integral part of the design of the pot itself, cast, or moulded during manufacturing.

[0054] In one embodiment, the at least one support of the container according to the invention is removable so that it can be easily replaced in the event of breakage or damage.

[0055] In one embodiment, the container according to the invention comprises multiple supports spaced apart from each other.

[0056] In some embodiments, the number of supports may vary from 3 to 8. In preferred embodiments, the number of supports may vary from 4 to 6.

[0057] In one embodiment, the multiple supports, in their support positions, engage a total support area, the value of which is between 3 and 30% of the flat area defined by the edge of the container base, preferably between 4 and 20%. A set of multiple supports ensures a more balanced weight distribution, which is especially important when the plants grown in the container grow rapidly and reach significant heights, as is the case with raspberry plants.

[0058] In one embodiment, multiple supports are arranged on said base to facilitate the stacking of two or more containers.

[0059] In one embodiment, the base of the container according to the invention is a substantially circular surface and said wall forms a cylindrical or frustoconical surface extending from the edge of the base.

[0060] In one embodiment, the base of the container according to the invention is a polygonal surface, the edge of the base is formed by three or more sides and the wall is formed by three or more facades extending from the respective three or more sides of the edge.

[0061] In one embodiment, the depression in the base of the container according to the invention is formed by a dome-shaped recessed surface.

[0062] In one embodiment, said dome-shaped recessed surface has a concave profile with a constant radius.

[0063] In another embodiment, said dome-shaped recessed surface has a concave profile with a variable radius.

[0064] In one embodiment, the depression present in the base of the container according to the invention is formed by a frustoconical or cylindrical recessed surface.

[0065] A base with a depression or concave recess in an object such as a pot or container offers a significant advantage for the movement of air underneath. This design is particularly useful for promoting air circulation between the base of the container and the supporting surface.

[0066] The depression creates an additional empty space, in addition to that created by the support(s), between the base of the container and the supporting surface, allowing air to circulate freely. This promotes aeration and therefore oxygenation of the plant roots and the formation of stagnant moisture under the container, which could cause problems such as mould, condensation, or unpleasant odours. Additionally, if the pot or container is used outdoors or in humid environments, the depression allows air to flow under the base, promoting rapid drying of the lower area. This is especially useful in applications that require good moisture management, such as containers for growing raspberries.

[0067] Additionally, the movement of air beneath the container helps to dissipate accumulated heat, especially if the container is exposed to the sun or placed on hot surfaces. This natural cooling effect prevents excessive heat build-up that could damage the container itself or its contents.

[0068] In one embodiment, the depression of the container according to the invention creates a space whose volume is between 0.7 and 3% of the capacity of said container.

[0069] In one embodiment, the depression is positioned in the central portion of said base and is surrounded by a connecting portion that extends from the perimeter of the base of the depression to the edge of the base.

[0070] The connecting portion can extend following a linear or curvilinear profile.

[0071] The connecting portion ensures even weight distribution and increases the stability of the container.

[0072] The configuration of the base, with its connecting portion and recessed surface, is optimised to ensure stability, durability and functionality, making it ideal for containers requiring high mechanical strength and balanced support during use.

[0073] The connecting portion can also be configured to couple multiple containers in a stackable or integrable manner, improving ease of storage and reducing the space required for transport.

[0074] In one embodiment, the connecting portion is inclined with respect to the plane containing the perimeter of the base of the depression.

[0075] In one embodiment, the connecting portion comprises at least two surfaces with different inclinations.

[0076] The particular configuration of the base of the container with the connecting portion inclined with respect to the plane containing the perimeter of the base of the depression facilitates the direction of the flow of liquids towards one or more drainage openings, improving the efficiency of draining water or other liquids accumulated inside the container.

[0077] In one embodiment, the at least one opening is positioned within the connecting portion.

[0078] In another embodiment, the at least one opening is positioned in the recessed surface of the depression.

[0079] In one embodiment, the at least one opening has dimensions compatible with the at least one support and is positioned on the base so as to facilitate the stacking of two or more containers.

[0080] In one embodiment, the base of the container includes multiple openings.

[0081] In one embodiment, the openings are positioned in both the connecting portion and the recessed surface of the depression.

[0082] The openings in the base of the container can be configured to perform a dual function: to allow liquids to drain from the container and to facilitate the stacking of multiple similar containers, ensuring a stable coupling between stacked containers.

[0083] In one embodiment, the wall of the container includes a plurality of surface discontinuity elements arranged in at least a portion of the inner surface of the wall.

[0084] For the purposes of describing the present invention, "surface discontinuity elements" shall be understood to mean any element that creates an interruption in the uniformity of a surface. Examples of "surface discontinuity elements" include, for example, grooves, ribs, ridges, or roughness on the surface, as well as protrusions and / or indentations created by curvatures of the surface itself.

[0085] In one embodiment, the surface discontinuity elements are grooves, ribs, reliefs and / or roughness present on the inner surface of said wall and / or protrusions and / or indentations created by curvatures of the wall itself.

[0086] The surface discontinuity elements are anti-spiral structures designed to prevent or reduce unwanted spiral or rotational movement of roots and / or fluids within the container. These anti-spiralization structures are, in fact, engraved or modelled on the inner surface of the container wall in such a way as to interrupt or deflect the spiral flow.

[0087] The surface discontinuity elements can be arranged parallel to the longitudinal axis of the container or at an angle such as to counteract the rotational movement.

[0088] The depth, width and spacing of these surface discontinuity elements are designed according to the characteristics of the substrate and the plant you to be grown and cultivated in the container.

[0089] In summary, the particular system of internal surface discontinuities of the container described above prevents the spiralization of the roots, allowing the root system of the plant to expand longitudinally.

[0090] In one embodiment, the wall of the container according to the invention includes one or more openings.

[0091] The openings in the container wall simultaneously improve both water and air circulation within the substrate.

[0092] These openings act as additional drainage holes for excess water, thus helping to prevent the soil from becoming soggy and causing root rot.

[0093] Furthermore, the presence of holes in the walls of the pot ensures greater air circulation within the substrate / soil, preventing the soil and roots from overheating and facilitating oxygenation of the roots and healthy root growth.

[0094] The container according to the present invention can be made of various materials, preferably plastic.

[0095] It is to be understood that, if any prior art is referred to herein, such reference does not constitute an admission that the prior art forms a part of the common general knowledge in the art.

[0116] DETAILED DESCRIPTION OF THE INVENTION

[0117] The solution according to the present invention will now be described with the reference to the drawings.

[0118] The invention described here relates to a container for growing plants, referred to collectively as reference 10.

[0119] The container 10 comprises a base 20, a wall 40 and at least one support 50. The base 20 defines the bottom of the container 10 and is delimited by an edge 22. The wall 40 extends from or near the edge of the base, while the at least one support 50 extends from the base in a direction opposite to the wall 40.

[0120] With particular reference to the embodiments shown in figures 1 to 14, the base 20 of the container is substantially square and is delimited by an edge 22 formed by four sides from which four panels extend to form a frustoconical wall.

[0121] In the exemplary embodiments shown in figures 1 , 3, 5, 7, 9, 11 and 13, the container 10 comprises six cylindrical supports 50 that extend from the base 20 in a direction opposite to the wall 40. In particular, the supports 50 have a support perimeter 52 and a side wall perpendicular to the supporting surface of the pot. The supports 50 are "closed," i.e. formed by a continuous outer surface that makes them impermeable to water or other fluids that may contain pathogens and parasites. The closed design of these supports 50 also makes the container more stable and robust.

[0122] In the exemplary embodiments shown in the figures, the supports 50 have a height of approximately 2.5 cm and, in a support position, occupy a total support area of approximately 4.5% of a flat area defined by the edge of the base of the container.

[0123] This height of the supports 50 allows for improved drainage and prevents the accumulation of moisture under the container 10, while also promoting better aeration of the roots.

[0124] The height and support perimeter 52 may vary depending on the shape or size of the container or according to the particular needs of the plant to be grown.

[0125] The support perimeter 52 of the support 50 of the container 10 according to the invention, being formed by a closed continuous line, creates a better distribution of the weight of the container, ensuring its stability.

[0126] This aspect is particularly important because supports made of open segments of material cannot evenly distribute the weight of the container and its contents, thus creating a buildup of pressure in the area directly beneath the supports. This buildup of pressure facilitates the penetration of the supports into the underlying ground reducing or even eliminating the distance between the base of the container and the underlying ground. The sinking of the supports, and thus the lowering of the base of the container towards the underlying ground, not only reduces or nullifies the function of the drainage holes in the bottom of the container, but also exposes the plant roots to potential pathogens and parasites that may rise from the soil or the supporting surface, including by air.

[0127] Furthermore, the circular support perimeter 52 of this exemplary embodiment, thanks to its edge-free design, tends to further prevent the supports 50 of the container 10 from damaging or cutting any eventual protective sheets underneath and / or sinking into the ground below.

[0128] The number, shape and arrangement of the supports 50 can be varied according to requirements.

[0129] For example, in the embodiment shown in Figure 16, the container 10 comprises four supports 50 arranged on a circular base 20. The supports 50 are equidistant from each other and arranged near the edge of the base 22 to ensure an even distribution of the weight of the container and its contents.

[0130] Returning to the description of the embodiments shown in figures 1 to 14, the base 20 of the container 10 is shaped with a central dome-shaped depression 30.

[0131] This depression 30 creates a space whose volume is approximately 1 % of the capacity of the container 10.

[0132] This specific ratio between the volume created by the depression 30 and the total volume of the container (capacity) ensures adequate water drainage, guaranteeing an optimal and uniform percentage of humidity inside the container. This volumetric ratio creates an optimal contact surface between the base 20 of the container 10 and the soil contained therein, promoting fluid drainage even from portions of soil that are more prone to waterlogging.

[0133] The inventors found that the particular volumetric ratio between the space created by the depression and the capacity of the container generally promotes optimal growing conditions for raspberry plants. However, this volumetric ratio can be modified depending on soil conditions and the type of plant to be grown.

[0134] The depression 30 of the base 20 of the container 10 in accordance with the embodiments shown in the figures, includes multiple openings 24 which are also designed to promote the drainage of excess fluids from the soil and, at the same time, adequate ventilation inside the container. In the embodiments shown in FIGS. 1 through 14, these drainage openings / holes 24 are oval in shape and extend radially from the centre to the perimeter of the base of the depression.

[0135] However, the shape, configuration and position of these drainage openings / holes 24 can be varied as desired and according to cultivation requirements.

[0136] Advantageously, the depression 30 in the base 20 facilitates the positioning of drainage openings / holes 24 in an elevated position relative to the plane containing the edge of the base 20, thus promoting better drainage and better oxygenation of the soil and the plant roots.

[0137] Furthermore, this depression 30 increases the contact surface of the base 20 of the container 10 with the air flow present between the base of the container and the supporting surface, improving the aeration inside the container 10 and consequently the oxygenation of the roots and the overall health of the plant.

[0138] Furthermore, the combination of the raised supports 50 and the depression 30 in the base 20 of the container 10 promotes air movement beneath the container 10, thereby preventing excessive heating or cooling of the base and facilitating the maintenance of more stable thermal conditions for plant cultivation.

[0139] The inventors found that the geometry of the depression 30 does not compromise the overall stability of the container 10 and can be configured with a continuous or variable inclination angle to optimize the outflow or stability properties of the contents.

[0140] In the exemplary embodiments shown in the figures, the depression 30 is positioned in the central part of the base 20 and is surrounded by a connecting portion 60 that extends from the perimeter of the base 32 of the depression 30 to the edge 22 of the base 20.

[0141] In the embodiments shown in the figures, the connecting portion 60 follows a linear profile. However, in other embodiments the connecting portion 60 may follow a curvilinear profile. In the embodiments shown in figures 1 to 14, the connecting portion 60 lies on the plane containing the perimeter of the base 32 of the depression 30 and the edge 22 of the base 20.

[0142] However, in other embodiments, the connecting portion 60 may lie on a plane substantially parallel to the plane containing the perimeter of the base 32 of the depression 30 or to the plane containing the edge 22 of the base 20.

[0143] In the embodiment shown in figures 15 and 16, the connecting portion 60 is inclined with respect to the plane containing the perimeter of the base 32 of the depression 30.

[0144] In this embodiment, the perimeter of the base 32 of the depression 30 is located on a different plane from that of the edge 22 of the base 20 of the container 10 and the connecting portion 60 is inclined in a sloping manner towards the plane containing the perimeter of the base 32 of the depression 30, thus promoting better drainage of the soil located near the wall of the container 10.

[0145] In the exemplary embodiments shown in the figures, the connection portion 60 also contains openings for draining fluids from inside the container.

[0146] In addition, in the exemplary embodiments shown in the figures, the connecting portion 60 includes openings 28 of dimensions compatible with the container supports, which, in addition to acting as drainage holes, can accommodate the supports 50 of another container 10 in order to facilitate the stacking of two or more containers 10 and, consequently, their storage and transport.

[0147] In the exemplary embodiments shown in the figures, the wall 40 of the container 10 includes surface discontinuity elements 42.

[0148] The surface discontinuity elements 42 facilitate an easy movement of the roots and their optimal arrangement, promoting healthy and vigorous growth of the raspberry plant even in unconventional environments.

[0149] These surface discontinuity elements 42, in the embodiments shown in figures 1 to 12, are formed by curvatures of the surface of the wall 40. These curvatures interrupt the linear trend of the surface of the wall 40 thus promoting the anti- spiralization of the plant roots during its growth.

[0150] The exemplary embodiments shown in figures 1 -2, 5-6 and 9-10 include two surface discontinuity elements 42 for each face of the wall 40 of the container 10, while the embodiments shown in figures 3-4, 7-8 and 11 -12 include three surface discontinuity elements 42 for each face of the wall 40 of the container 10.

[0151] However, the number and arrangement of these surface discontinuity elements 420 can vary depending on cultivation needs.

[0152] Furthermore, these surface discontinuity elements 42 may be formed by different types of surface curvatures or may be formed by grooves, ribs, reliefs and / or roughness on the internal surface of the wall 40.

[0153] For example, in the embodiments shown in figures 13 and 14, the surface discontinuity elements 42 are grooves in the inner wall of the container 10.

[0154] In the exemplary embodiments shown in figures 5 to 14, the wall 40 of the container 10 includes openings 44 which generally serve to promote the drainage of excess water and facilitate ventilation inside the container 10.

[0155] The openings 44 located on the wall 40 near the position of the supports 50 of the container 10 are particularly important as they avoid the stagnation of liquids that can form in the area above the closed support 50.

[0156] EXPERIMENTAL PART

[0157] The experimental campaign was conducted at Molari Societa Agricola SS, Via Cerchia di Martorano, 891 , 47521 Cesena (FC), which was responsible for growing the raspberry plants in different types of pots and harvesting the fruit. The Department of Agricultural, Food, and Agro- Environmental Sciences at the University of Pisa was tasked with analysing the quality of the harvested fruit and, at the end of the growing period, analysing the growth of the plants used in the experimental campaign. Easy Star raspberry plants were planted in pots on March 7, 2024, while the plants were repotted with the various types of pots a few days later, on March 20, 2024. Fruit harvesting began on July 19, 2024, and continued until August 20, 2024, on a daily basis during the first week and four times a week during the remaining period. The fruits, harvested separately from each monitored plant (five plants per treatment), were weighed.

[0158] The pots compared were:

[0159] 1 ) the pot according to the present invention, in the configuration shown in figure 13 and figure 14, with a capacity of 7L and a square base (Vinv);

[0160] 2) a pot from the Dutch company Beekenkamp Plants, model 7407, marketed specifically for the cultivation of raspberries, with a capacity of 7 L and a square base (Vbeek), better represented in figures 17 and 18;

[0161] 3) a traditional nursery pot, also normally used for growing raspberries, with a capacity of 7 L and a circular base (Vstd), better represented in figure 19.

[0162] In particular, the experimental campaign aimed to verify whether the use of the pot according to the invention (Vinv) allowed to achieve advantages in terms of plant growth and health, highlighted in particular by the vitality of its roots after a certain period of observation, as well as by the quality of its fruits.

[0163] The experimental determinations on the morphological aspect of the plants and on the quality of their production were carried out on 23 July 2024 and concerned: a) the non-destructive morphological survey to assess the growth and therefore the height of the plant, as well as the destructive survey to assess the health index of the root system; b) the analysis of the fruit, determining the percentage of dry matter, titratable acidity, pH, overall antioxidant capacity, total phenol and flavonoid content.

[0164] The above tests and their results are reported in detail below.

[0165] Morphological surveys

[0166] On July 23, the height of the plants involved in the experiment was measured. Subsequently, the plants were removed from their pots and a visual assessment of the health of the root system was carried out, assigning a score between 1 and 5 according to the following scale:

[0167] 1 : roots completely browned;

[0168] 2: white roots present in at least 25% of the root system;

[0169] 3: white roots present in at least 50% of the root system;

[0170] 4: white roots present in at least 75% of the root system;

[0171] 5: white roots present in more than 75% of the root system.

[0172] All assessments were carried out in 5 replicates. Table 1 below reports the results obtained, expressed as the mean value for each treatment.

[0173] Table 1 - Results of morphological surveys of raspberry plants grown in three different types of pots.

[0174] As evident from the results reported in the table, the height growth of the plants was comparable in the three cases, but root health was significantly was clearly superior in the case of the Vinv pot according to the invention.

[0175] This index is even higher by about 36% compared to the index of Vbeek pot.

[0176] This greater healthiness can reasonably be attributed both to the use of closed supports in the case of the pot of the invention Vinv which, unlike the comparison pot Vbeek, pathogens from rising from the soil, thus better preserving the health of the root system, and to the presence of a more draining bottom.

[0177] Fruit analysis

[0178] The fruits were analyzed to determine their dry matter percentage, pH, titratable acidity, overall antioxidant capacity, total phenol and flavonoid content.

[0179] Dry matter

[0180] The fruit sample is weighed and placed in a ventilated oven at 70°C until it reaches a constant weight. The dry weight value of the substance is simply calculated using the following formula: dry weight / fresh weight x 100.

[0181] All assessments were carried out in triplicate for each pot used. pH, titratable acidity

[0182] Each fruit sample was homogenized in a mortar to obtain fruit juice.

[0183] The pH of the juice was measured with a benchtop pH meter (GLP21 , Orison, Barcelona, Spain).

[0184] Subsequently, 1 g of fruit pulp diluted with 30 mL of distilled water was titrated with 0.1 N NaOH until pH 8 was reached. The titratable acidity (TA) was expressed as % malic acid. All analyses were performed with 3 replicates per treatment.

[0185] Total phenol content

[0186] Total phenol content was determined as reported by Dewanto et al. (2002) with some modifications.

[0187] For extraction, 0.1 g of fresh plant material was homogenized in 1 mL of 80% (v / v) methanol solution and centrifuged at 10,000 rpm for 10 min at 4 °C.

[0188] For the test, 62.5 pL of extract aliquot was added to a solution composed of 250 pL milliQ H2O, 62.5 pL Folin- Ciocalteu reagent. Then, after 6 min of reaction, 625 pL of 7% (w / v) Na2CO3 and 500 pL milliQ H2O were added. The absorbance of the blue colour due to the reduction of metals present in the phosphomolybdate / phosphotungstate solution of the Folin-Ciocalteu reagent and the oxidation of phenolic compounds was measured at 760 nm with a spectrophotometer (Ultrospec 2100 Pro, GE Healthcare Ltd., Chalfont, RA, USA). Each measurement was compared to a standard curve of gallic acid (concentration range 30-600 pg mL-1 ) and the total phenol content was expressed as mg gallic acid equivalents (GAE) per g DW. 2.5.

[0189] Antioxidant activity

[0190] Antioxidant activity was measured as reported by Brand-Williams et al. (1995) by measuring the DPPH scavenging activity of the plant material under examination.

[0191] A 10 pL aliquot of phenolic extract was added to 990 pL of a methanolic solution of 3.12 x 10-5 M DPPH (w / v) and left for 30 min. The DPPH radical quenching by the antioxidant compounds was measured at 515 nm against a blank solution (without extracts) with the same spectrophotometer as above.

[0192] Each measurement was compared to a Trolox standard curve (concentration range 0-10 pM) and the AA was expressed as mg Trolox equivalents (TE) / 100 g PF.

[0193] Total flavonoid content (TFC)

[0194] Total flavonoid content was determined following the procedure described by Silva et al. (2014). A 100 pL aliquot of fruit extract was mixed with 30 pL of 5% (w / v) NaNO2 aqueous solution and 400 pL of distilled water. After 5 min, 30 pL of 10% (w / v) AICI3 aqueous solution was added to form aluminium-flavonoid complexes. After 6 min, 200 pL of 1 M NaOH and 240 pL of distilled water were added to the mixture.

[0195] The absorbance at 510 nm was measured spectrophotometrically against a blank solution for each extract replicate (which contained all reagents except 10% (w / v) AlCh aqueous solution, which was replaced with distilled water).

[0196] All obtained results (n = 5) were compared with a catechin standard curve (y = 0.0005x + 0.0465; R2 = 0.9956) and were expressed as mg catechin equivalents per 100 g FW (mg CAE 100 g-1 FW).

[0197] The results of all these tests carried out on the fruits, and expressed as average values of the various replicates, are reported in the following table 2.

[0198] Table 2 - results of tests carried out on fruits obtained from raspberry plants grown in three different pots.

[0199] As a result of the tests carried out, as is evident, only the pH was not significantly influenced by the type of pot used for cultivation. For all other observation parameters, the results regarding the quality of the fruit were nothing short of surprising.

[0200] The dry matter of the raspberries grown in the Vinv pot according to the invention was even approximately 21.5% higher than the dry matter of the Vbeek pot and approximately 10% higher than that of the standard nursery pot Vstd.

[0201] The titratable acidity also proved to be much higher and all the parameters strictly linked to the nutritional value of the fruit, in terms of antioxidant characteristics, were found to be significantly and unexpectedly higher.

[0202] In fact, an increase in the total phenol content of approximately 19.8% was found in the case of cultivation with the Vinv pot according to the invention, compared to the comparison pot Vbeek and of 12.9% compared to the standard nursery pot Vstd.

[0203] An increase in antioxidant activity of approximately 10.5% was also observed when growing in the Vinv pot according to the invention, compared to the comparison pot Vbeek and of 17.9% compared to the standard nursery pot Vstd.

[0204] Finally, an increase in the total flavonoid content of approximately 24.17% was observed in the case of cultivation with the Vinv pot according to the invention, compared to the comparison pot Vbeek and of even 54.8% compared to the standard nursery pot Vstd.

[0205] These values indicate unequivocally that the geometry designed for the pot according to the invention, which features closed support feet spaced from the ground to protect the roots from pathogen attacks, and appropriate recesses and holes for proper drainage and aeration of the substrate, have made it possible to grow healthy, vigorous blueberry plants capable of producing fruit of the highest quality.

[0206] Finally, determining the quantity of fruit produced by the different plants grown in the different pots led to further provided further evidence of superior productivity.

[0207] Plants grown in the Vinv pot according to the invention showed a productivity 25% higher than plants grown in the Vbeek pot and even double the productivity of the standard nursery pot Vstd. It has therefore also been experimentally demonstrated how the container according to the present invention allows for the reduction or elimination of the main obstacles associated with container-grown cultivation, such as root spiralization, pathogen contamination, waterlogging and incorrect oxygenation of the root system.

[0208] The combination of the characteristics of the container according to the present invention allows to improve the quality of the fruit and reduce the environmental impact by promoting healthy and vigorous growth of the raspberry plant even in unconventional environments.

[0209] Finally, the container according to the present invention also allows for easy handling and storage.
