Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a method for producing Tainong No. 1 mango embryoless fruit. Background Art

[0002] At present, the production of seedless fruits at home and abroad has mature technology for some fruit varieties, such as grapes and lychees. Because seedless fruits are easy to eat fresh and have a high edible rate, they are suitable for a wider range of people, especially the elderly and children. And because seedless fruits are easier to process, they are very popular in the market. However, there are few studies and reports on the research and utilization of mango embryo aborted fruits at home and abroad, especially no relevant reports on the production technology of Tainong No. 1 mango embryoless fruit.

[0003] The embryoless mango fruit of Tainong No. 1 produced in Baise has been highly praised by the national mango processing industry for its rich aroma and flavor, high soluble solids and edible rate. Among mango processed products such as mango tea, juice, pulp, and preserved fruit, Baise Tainong No. 1 mango embryoless fruit is the main processing object, and similar products from other production areas are used as auxiliary. Therefore, the market demand for Baise Tainong No. 1 mango embryoless fruit has continued to rise in recent years.

[0004] In addition to the smaller individual fruit size (approximately 50g when grown naturally), the average individual fruit weight of Tainong No. 1 embryoless mango obtained through existing management methods is less than 90g. However, due to its small core, its edible rate is higher than that of normal fruit, and its flavor, sugar content and other qualities are also better than normal fruit. Currently, there are no stable and reliable agronomic measures to mass-produce Tainong No. 1 embryoless mango with a single fruit weight greater than 100g.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0006] The purpose of the present invention is to provide a method for producing Tainong No. 1 Mong embryoless fruit, aiming to overcome the lack of stable and reliable agronomic measures on the market for mass production of Tainong No. 1 Mong embryoless fruit with a single fruit weight greater than 100g, large transverse diameter, longitudinal diameter and lateral diameter, and thin core.

[0035] Example 1

[0036] A method for producing Tainong No. 1 mango embryoless fruit, comprising:

[0037] Apply pesticides from the young mango fruit stage, 4 times, with an interval of 7-10 days between each application. The specific application steps are as follows:

[0038] (1) First application (April 9, 2024): When the mango enters the young fruit stage, that is, when the mango fruit grows to 0.5 mm (soybean size), choose a sunny day to evenly spray solvent A on the fruit surface to completely wet the fruit surface. The solvent A is prepared by taking 2.4 mL of 3% gibberellin agent, 2.4 mL of peptide calcium magnesium, 0.75 mL of 0.01% 2,4-epibrassinolide, 1 mL of 3.6% benzylamino gibberellic acid solvent, and 3.0 mL of 2% benzylaminopurine, adding them to 3000 mL of water and mixing and dissolving them thoroughly;

[0039] (2) Second application (April 18, 2024): Choose a sunny day to spray solvent B evenly on the fruit surface, and do not drip water on the fruit surface. The preparation method of solvent B is to take 3.6 mL of 3% gibberellin agent, 1.8 mL of 3.6% benzylamine·gibberellic acid solvent, 3.0 mL of 2% benzylaminopurine, 4.8 mL of chlorfenapyr and 2.4 mL of sugar alcohol calcium, 2.5 mL of medium element water-soluble fertilizer (specialty), and 7.5 mL of trace element water-soluble fertilizer (golden banana awn) and add them to 3000 mL of water and mix and dissolve them thoroughly;

[0040] (3) The third application of pesticide (April 26, 2024): Choose a sunny day to spray solvent C evenly on the fruit surface, and make sure that there is no water dripping on the fruit surface. The solvent C is prepared by adding 4.8 mL of 3% gibberellin agent, 1.8 mL of 3.6% benzylamino gibberellic acid solvent, 3.0 mL of 2% benzylaminopurine, 6.0 mL of chlorfenapyr, 0.07 g of 50% thidiazuron, 3.0 mL of medium element water-soluble fertilizer (specialty), 7.5 mL of trace element water-soluble fertilizer (golden banana mango) and 0.75 mL of ampicillin to 3000 mL of water and mixing and dissolving them thoroughly;

[0041] (4) Fourth application (May 4, 2024): Choose a sunny day to spray solvent D on the fruit surface, with no water dripping from the fruit surface. The solvent D is prepared by adding 3.0 mL of 3% gibberellin agent, 1.8 mL of 3.6% benzylamine·gibberellic acid solvent, 3.53 mL of boron fertilizer (special), 0.08 g of 50% thidiazuron, 4.8 mL of chlorfenapyr and 2.4 mL of sugar alcohol calcium, and 7.5 mL of trace element water-soluble fertilizer (golden banana awn) into 3000 mL of water and mixing and dissolving them thoroughly;

[0042] In steps (1) to (4), the interval between spraying can be appropriately shortened when the maximum daily temperature is above 35°C, and the interval between spraying can be appropriately extended when the maximum daily temperature is lower.

[0043] (5) During the application of pesticides, root fertilizer management is used as follows:

[0044] Root fertilization: When the fruit grows to 10-20mm (peanut size), apply 0.50-0.75kg / plant amino acid water-soluble fertilizer to the roots once; when the fruit grows to 40-50mm (egg size), apply 0.50-0.75kg / plant amino acid water-soluble fertilizer and 0.40kg / plant high-potassium instant fertilizer to the roots once.

[0045] The Tainong No. 1 mangoes were processed according to the method of Example 1. The processing methods of the embryo fruit group and the embryoless fruit group were processed using the currently commonly used mango planting method. The fruit data of the three groups of mangoes after maturity are shown in Table 1 below.

[0046] Table 1 Fruit situation table of embodiment 1, embryo fruit and conventional embryoless fruit

[0047]

[0048] As can be seen from Table 1, the single fruit weight, longitudinal diameter, transverse diameter and lateral diameter of the embryo-containing fruit planted by the prior art are significantly greater than those of the embryoless fruit planted by the prior art, while the embryoless fruit of the method of the present invention starts to apply pesticides at a specific time of the selected fruit, and the single fruit weight of the embryoless fruit of Tainong No. 1 Mang is significantly increased by selecting the composition of the pesticide, and the longitudinal diameter, transverse diameter and lateral diameter are increased, thereby significantly increasing the fruit specifications and single fruit weight of the embryoless fruit of Tainong No. 1 Mang, so as to improve the economic value and market competitiveness of the embryoless fruit of Tainong No. 1 Mang.

[0049] Comparative Examples 1-4

[0050] The difference from Example 1 is that the compositions of the solvent A for the first application, the solvent B for the second application, the solvent C for the third application, and the solvent D for the fourth application of Comparative Examples 1-4 are different;

[0051] On April 9, 2024, solvent A was evenly sprayed on the mango fruit surfaces of each group of Example 1 and Comparative Examples 1-4, respectively. The component ratios of solvent A in Example 1 and Comparative Examples 1-4 were different. The components of solvent A in the first application of Example 1 and Comparative Examples 1-4 were different as follows:

[0052]

[0053] The transverse diameter (mm), longitudinal diameter (mm) and lateral diameter (mm) of mangoes in each group of Example 1, Comparative Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4 were measured on April 17, 2024. The conditions of the mango fruits in Example 1 and Comparative Examples 1-4 are shown in Tables 2 and 3 below.

[0054] Table 2: The size of mango fruits in Example 1 and Comparative Example 1-2

[0055]

[0056]

[0057] As can be seen from Table 2, the longitudinal diameter, transverse diameter and lateral diameter of the mango fruits of Comparative Examples 1-2 have similar values ​​and similar average values, while the longitudinal diameter of the mango fruits of Example 1 is significantly larger than that of the mango fruits of Comparative Examples 1-2, and the transverse diameter and lateral diameter of the mango fruits of Example 1 are slightly larger than those of the mango fruits of Comparative Examples 1-2.

[0058] Table 3: The size of mango fruits in Example 1 and Comparative Examples 3-4

[0059]

[0060] As can be seen from Table 3, the fruit size growth of Example 1 and Comparative Example 3 is similar, while the size of Comparative Example 4 is much smaller than that of Example 1 and Comparative Example 3 because no chemical agent is applied.

[0061] On April 18, 2024, solvent B was evenly sprayed on the mango fruit surfaces of each group of Example 1 and Comparative Examples 1-4, respectively. The component ratios of solvent B in Example 1 and Comparative Examples 1-4 were different. The components of solvent B in the second application of Example 1 and Comparative Examples 1-4 were different as follows:

[0062]

[0063] The transverse diameter, longitudinal diameter and lateral diameter of mangoes in each group of Example 1, Comparative Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4 were measured on April 26, 2024. The conditions of the mango fruits in Example 1 and Comparative Examples 1-4 are shown in Tables 4 and 5 below.

[0064] Table 4: The size of mango fruits in Example 1 and Comparative Examples 1-2 after secondary fertilization

[0065]

[0066]

[0067] As can be seen from Table 4, in Comparative Example 1, no growth regulator was used for the mango fruit, and its longitudinal diameter, transverse diameter and lateral diameter were significantly lower than those in Example 1 using the growth regulator. In Comparative Example 2, where only gibberellin was used as the growth regulator, its longitudinal diameter, transverse diameter and lateral diameter were slightly larger than those in Comparative Example 1, but its growth was much weaker than that in Example 1.

[0068] Table 5: The size of mango fruits in Example 1 and Comparative Examples 3-4 after the second application of pesticides

[0069]

[0070] As can be seen from Table 5, in Comparative Example 3, the mango fruits used Naipu 9 as the medium-element water-soluble fertilizer and Ferraro as the trace-element water-soluble fertilizer, and the longitudinal, transverse and lateral diameters were slightly lower than those in Example 1 using Zhuanchang and Jinjiaomang. In Comparative Example 4, the longitudinal, transverse and lateral diameters of the mangoes applied with gibberellin and 2% benzylaminopurine grew faster, but due to one less round of application, the overall fruit shape was smaller than that of Comparative Examples 1-3.

[0071] On April 26, 2024, solvent C was evenly sprayed on the mango fruit surfaces of each group of Example 1 and Comparative Examples 1-4, respectively. The component distribution ratios of solvent C in Example 1 and Comparative Examples 1-4 were different. The components of solvent C in the first application of Example 1 and Comparative Examples 1-4 were different as follows:

[0072]

[0073]

[0074] The transverse diameter, longitudinal diameter and lateral diameter of mangoes in each group of Example 1, Comparative Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4 were measured on May 5, 2024. The conditions of the mango fruits in Example 1 and Comparative Examples 1-4 are shown in Tables 6 and 7 below.

[0075] Table 6 The size of mango fruits in Example 1 and Comparative Example 1-2 after three applications

[0076]

[0077] It can be seen from Table 6 that the size of mangoes in Example 1 is much larger than that in Comparative Examples 1 and 2.

[0078] Table 7 The size of mango fruits in Example 1 and Comparative Examples 3-4 after three applications

[0079]

[0080] As can be seen from Table 7, the difference between Example 1 and Comparative Example 3 is that the fertilizers used are medium-element water-soluble fertilizer Expertise and trace-element water-soluble fertilizer Golden Jiaomang, while Comparative Example 3 uses Guofeng 99 microbial fertilizer. As a result, the fruit growth of Example 1 is greater than that of Comparative Example 3 after 8 days of treatment.

[0081] On May 5, 2024, solvent D was evenly sprayed on the mango fruit surfaces of each group of Example 1 and Comparative Examples 1-4, respectively. The component distribution ratios of solvent D in Example 1 and Comparative Examples 1-4 were different. The components of solvent D in the first application of Example 1 and Comparative Examples 1-4 were different as follows:

[0082]

[0083]

[0084] The transverse diameter, longitudinal diameter and lateral diameter of mangoes in each group of Example 1, Comparative Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4 were measured on May 13, 2024. The conditions of the mango fruits in Example 1 and Comparative Examples 1-4 are shown in Tables 8 and 9 below.

[0085] Table 8 The size of mango fruits in Example 1 and Comparative Example 1-2 after four applications

[0086]

[0087] As can be seen from Table 8, the growth of Example 1 after using solvent D has slowed down, indicating that the effects of growth hormones and fertilizers on promoting mango growth are gradually reduced, and the spraying of growth regulators to promote fruit enlargement can be reduced or even stopped.

[0088] Table 9: The size of mango fruits in Example 1 and Comparative Examples 3-4 after four applications

[0089]

[0090] When the mangoes in Example 1 and Comparative Examples 1-4 reached the picking period, the longitudinal diameter, transverse diameter, lateral diameter and core thickness of the mangoes were tested. The results are shown in Table 10.

[0091] Table 10: Mango size of each group of examples during the picking period

[0092]

[0093] In Comparative Example 1, gibberellin and 2,4-epibrassinolide were added to solvent A, and only foliar fertilizer was added to the subsequent several applications as a blank control. The mango fruit obtained by the treatment method of Comparative Example 1 grew normally, the embryo fruit kernel developed normally, the embryoless fruit did not fully expand, and the single fruit weight was less than 100g; Comparative Example 2 shows that the application method can play a certain role in expanding the fruit, but the fruit expansion effect is not obvious; Comparative Example 3 shows that adding different types of medium-element water-soluble fertilizers and trace-element water-soluble fertilizers to the applied agent or even not adding them can better achieve the embryonic fruit abortion and fruit expansion indicators, but has a slight effect on the transverse diameter, longitudinal diameter and lateral diameter growth of mangoes during the expansion period and the final single fruit weight of Tainong No. 1 mango without embryos; Comparative Example 4 applied the medicine late, and did not start applying the medicine when the mango was the size of a soybean. Although it can effectively expand the fruit, the final Tainong No. 1 mango without embryos is much smaller than that of Comparative Example 3 and Example 1.

[0094] Some mangoes from each embodiment were taken to test the storage conditions, and the following experiment was conducted: they were stored at 26-35° C. for 9 days, and the number of good fruits was observed every day. The results are shown in Table 11 below.

[0095] Table 11 Storage conditions of mangoes in various embodiments

[0096]

[0097] Note: The data in the table are the number of good fruits

[0098] At present, the Tainong No. 1 mango embryoless fruit of the present invention is being planted in demonstration in Tianyang, Tiandong, Tianlin and other places, and the planting conditions and fruit bearing conditions are shown in Table 12 below.

[0099] Table 12 2024 Tainong No. 1 Mango Embryo-free Fruit Experimental Demonstration Base Yield Check Table

[0100]

[0101] It can be seen from Table 12 that this method can stably obtain embryoless fruits, with an average embryoless fruit rate of 98.14%, indicating that this method can be used for mass production of embryoless fruits of Tainong No. 1 Mango. Furthermore, the average single fruit weight of the embryoless fruits obtained is above 110 g, with good quality.

[0102] The present invention can be implemented in various ways and is not limited to the embodiments described. A person skilled in the art can understand that the present invention can be implemented in other specific ways without changing the technical concept or essential features of the present invention. Therefore, it should be understood that the embodiments described above are exemplary and are not intended to limit the present invention.
