European and American hybridized grape seedless treatment method

Abstract

A method for culturing the non-seed crossed Oumei grape includes such steps as preparing the solution from streptomycin sulfate, gibberellin and distilled water, immersing the bunches of flower in the solution from the 6 days before blossoming 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 seedless treatment method for European-American hybrid grapes, which is used for cultivating seedless large-grain European-American hybrid grapes, and belongs to the technical field of agricultural and forestry crop cultivation. Background technique: [0002] Seedless grapes are popular among consumers without the trouble of spit out seeds. But the germplasm resource of producing natural seedless variety is not too abundant at present, and natural seedless grape generally shows the shortcoming that fruit particle is too small, can't satisfy consumer's demand to seedless grape. The effective technical measure that solves the problems referred to above is to adopt denuclearization technology to the seeded grape variety that has been cultivated in production, so that it produces seedless large-grained grapes. The use of gibberellic acid (GAs) to induce the seedless production of nucleated varieties was first successful on the ...

Problems solved by technology

[0003] Looking at domestic and foreign grape seedless cultivation techniques, there are still three deficiencies: (1) Although it has achieved success in the varieties of "Rose Dew", "Muscat berry A" and "Pione", But to the kind with lower tendency of denuclearization such as Kyoho, Fujiminori, etc., the main planted nucleated large-grained varieties, the use effect is very unsatisfactory; (2) the price of the non-nuclear inducer is expensive, and the cost is too high (current domestic chemical The price of gibberellic acid in the reagent store is about 125 yuan / 100mg), and it is difficult to popularize under the condition of low grape price in my country; (3) the effective treatment time is short, and the general variety is only 3 days, so it is very difficult to apply in a large area
