A kind of preparation method of grape seedless agent

Abstract

The invention discloses a preparation method for an agent used for production of seedless grapes. The agent is prepared from certain amounts by weight of gibberellin, B9, forchlorfenuron and 2,4-dichlorphenoxyacetic acid and 10% of ethanol. After the agent is applied to flower clusters and fruit clusters, the seedless rate of grapes can reach 100%, seedless grapes are bigger in size, the period of keeping grapes on grapevines for fresh storage is prolonged, and a fruit setting rate is increased. The agent is simple to prepare and can be easily absorbed by the flower clusters and the fruit clusters.

Description

Technical field [0001] The invention relates to a plant growth regulator, in particular to a preparation method of a grape seedless agent. Background technique [0002] Grape seedless technology was first created in Japan in the 1950s. People use gibberellin to treat grape flower spikes and young fruits to obtain basically seedless fruits and ripen early. Since then, people at home and abroad have continued to conduct experiments and research, and some seedless agents have also been used in production in China, such as: grape seedless agents No. 1 and 2 from the Fruit Tree Institute of Jilin Academy of Agricultural Sciences; "Youguo" from China Agricultural University "Xiaoziling" from a research institute in Xinyang, Henan; "Mengwa I" from Shaanxi Yangling Dacheng Agricultural Technology Co., Ltd.; Liaoyang Yang Xiuwen's grape seedless agent, etc. Although these technologies can basically denuclearize certain varieties (with a seedless rate of over 90%) and mature earlier, they...

AI Technical Summary

Problems solved by technology

Although these technologies can basically make some varieties denuclearized (the denuclearization rate reaches more than 90%), and mature early, they all fail to solve the following problems:

[0003] 1. It is not possible to make the seedless rate of different varieties reach 100%;

[0004] 2. The seedless fruit becomes smaller, and the seedless fruit cannot be made larger than the seeded fruit;

[0005] 3. It can mature early, but it cannot be hung on the tree for long-term fresh storage, so as to prolong the supply period of fresh fruit

But this method mentions to use water to dissolve, and is less soluble in water by gibberellic acid, 6-benzylaminopurine, α-naphthalene acetic acid, fenfenzuramide, 24-epibrassinolide, Tween 20, It is difficult to prepare a seedless agent that is easy to apply; and the preparation with alcohol can dissolve the above-mentioned growth regulators, but the concentration of ethanol is too high, which is not conducive to the absorption of flower spikes and fruit spikes.
