The present invention relates to a sorter roller (1) for a sorting table allowing the removal of foreign bodies that remain mixed with the products of the harvest of small fruits, more particularly small fruits such as grape berries after destemming the grape harvest, the sorting table including a series of sorter rollers (1) arranged so as to provide a plurality of screening openings through which the small fruits to be sorted can pass and fall, the sorter roller (1) having a series and an alternation of regularly spaced grooves (10) and ridges (11), each ridge (11) extending around the longitudinal axis (X) of the sorter roller (1) in a ridge plane perpendicular to the longitudinal axis (X) of the sorter roller (1), each groove (10) having a concave outer surface resulting from the rotation of the rotational profile of the groove (10) about the longitudinal axis (X) of the sorter roller (1) and connecting two adjacent ridges (11), namely a first ridge (11) and a second ridge (11). The invention is characterised in that the rotational profile of each groove (10) is asymmetrical. The invention also relates to a sorting table comprising a series of such sorter rollers.

This technology provides targeted genome editing techniques for altering the color of parts of grape plants and their fruits. Specifically, this technology relates to using genome editing methods to generate edits in target genes that cause large fragment inactivation deletions, thereby altering the color traits of plants and fruits. These target genes include genes and genetic elements associated with plant color and pigment deposition (e.g., the PDS1 gene, the mybA1 gene, and the Gret1 retrotransposon).

This invention belongs to the field of grape cultivation technology, specifically relating to a fruit enlargement agent for Daqing grapes, its preparation method, and its application. The fruit enlargement agent for Daqing grapes is prepared from an aqueous solution of gibberellin, thiabendazole, and brassinolide. Specifically, the concentration of gibberellin in the fruit enlargement agent is 20 mg / L~25 mg / L, the concentration of thiabendazole is 1.0 mg / L~1.25 mg / L, and the concentration of brassinolide is 0.025 μg / L~0.050 μg / L. The fruit enlargement agent of this invention, combined with fruit thinning treatment, can increase the weight of a single Daqing grape berry by at least 20% while retaining the soluble solids content of the grape.

The invention relates to a composition for making a tea beverage, the composition comprising tea which may be ground tea in combination with plant cell culture grown in vitro in a large scale. The plant cell culture grown in vitro in a large scale may be derived from any plant, such as a fruit including but not limited to grape berry, pomegranate, olive, and the like. The composition may be inserted into a pod and be used in a machine or inserted into a tea bag or a container.

This utility model relates to a vibrating sieve for selecting grape berries for winemaking, comprising: a destemming mechanism for separating grape berries and stems; a vibrating sieving mechanism for sieving to remove fine impurities and rotten grapes; a stem guiding mechanism including a hinged, swing-mounted, grid-like guide component; and a stem-removing mechanism including a hollow roller rotatably mounted below the guide component, the surface of which is equipped with a lever that is interleaved with the grid on the guide component; when the hollow roller drives the lever to rotate, it pushes the stems intercepted by the guide component upwards and transfers them to the stem conveyor belt. This utility model replaces the traditional multi-layer grading guide roller method of separating grape berries by adding a stem guiding mechanism and a stem-removing mechanism to remove stems, effectively solving problems such as incomplete grape separation and grapes easily getting stuck between the guide rollers and causing damage.

This invention provides strigolactone via VvORR9 The methods and applications of gene regulation of grape berry shape belong to the fields of plant molecular biology and agricultural biotechnology. This study involves regulating grape berry shape through exogenous application of the synthetic strigolactone analog GR24. VvORR9 Gene expression levels alter the longitudinal and transverse diameters of the fruit, as well as the fruit shape index. This invention, combining correlation analysis, stable transformation in grapes, and heterologous transformation in tomatoes, constructs a molecular regulatory network for strigolactone-mediated grape fruit shape regulation. It is the first to demonstrate that the strigolactone signaling pathway participates in grape fruit morphogenesis and identifies regulatory factors that respond to strigolactone. VvORR9 This provides a theoretical basis for the precise regulation of grape fruit shape and molecular breeding.

This invention belongs to the fields of fruit and vegetable science and gene technology, and discloses the application and vector of the grape VvNAC17 gene in regulating postharvest grape berry abscission. The gene sequence of the VvNAC17 gene is shown in SEQ ID NO.1, and the amino acid sequence of its encoded protein is shown in SEQ ID NO.2. The VvNAC17 silencing technology of this invention provides precise regulation at the gene molecular level, reducing the uncertainties of external environment and storage and transportation conditions, significantly reducing berry abscission rate, and improving the marketability and economic benefits of grapes during storage and transportation. By constructing a VvNAC17-RNAi vector, this invention verifies for the first time the key positive regulatory role of the VvNAC17 gene in postharvest berry abscission. The gene silencing technology does not rely on complex storage and transportation conditions and avoids the potential impact of chemical agents on fruit quality and the environment, providing an innovative solution for modern grape storage and transportation technology.
