Problems solved by technology

[0003] Taking a comprehensive view of grape seedless cultivation techniques at home and abroad and the seedless agents adopted, there are still 3 deficiencies at present: (1) although the effect of seedless induction on European and American hybrid grape varieties is better, but the seedless induction effect on Eurasian grape varieties (2) the price of the non-nuclear inducer is expensive, and the cost is too high (the price of gibberellic acid in the domestic chemical reagent store is about 125 yuan / 100mg), and it is difficult to popularize under the low price of grapes in my country (3) The effective treatment time is short, only 3 days for general varieties, and it is very difficult to apply in large areas

Embodiment Construction

[0009] 1. Preparation of seedless agent: The formula of Eurasian grape seedless agent provided by the present invention is: 200 mg / L streptomycin sulfate (MS) and 50 mg / L gibberellin (GA s ) Mixed solution, namely MS 200mg / L+GA s 50mg / L. The preparation method is as follows: Weigh 200 mg of streptomycin sulfate powder (produced by Shanghai No. 4 Pharmaceutical Factory, with a purity of 700,000 units) with an electronic balance, add 20-30 ml of distilled water to dissolve, transfer all to a 1000 ml volumetric flask; then use electronic Weigh 50 mg of gibberellin powder (produced by Shanghai Solvent Factory, with a purity of 99%) on the balance, add 10-20 ml of alcohol to dissolve, transfer all to a 1000 ml volumetric flask; finally add distilled water to a 1000 ml volumetric flask, and dilute to 1000 Milliliter is enough.

[0010] 2. Use seedless agent to denucleate Eurasian grapes: (take the "rose fragrance" variety as an example)

[0011] The first treatment: 6 days before the bl...

Abstract

A method for culturing the non-seed Ouya grape includes such steps as preparing the solution from streptomycin, gibberellin and distilled water, immersing the bunches of flower in the solution from the 6 days before bloosoming to the 3 days after blossoming, preparing the solution of gibberellin or forchlorfenuron, and treating the grapes with the solution about 14 days after blossoming. Its non-seed ratio can reach more than 95%.

Description

Technical field: [0001] The invention relates to a denuclearization processing method for Eurasian grapes, which is used for cultivating seedless large-particle Eurasian grapes, and belongs to the technical field of agricultural and forestry crop cultivation. Background technique: [0002] The cumbersomeness of seedless grapes without spitting up seeds is very popular among consumers. However, the germplasm resources of natural seedless varieties are not very abundant at present, and natural seedless grapes generally show the shortcoming of small fruits, which cannot satisfy consumers' demand for large seedless grapes. An effective technical measure to solve the above-mentioned problems is to use denuclearization technology for the cultivated seeded grape varieties to produce seedless large-grain grapes. The key to denuclearization technology is the selection and use of denuclear agents. The use of gibberellic acid (GAs) to induce seedless production of nucleated varieties has be...
