Agent for obtaining seedless grape

Abstract

The invention discloses an agent for obtaining seedless grapes, comprising the following components in percentage by weight: 1-3 percent of gibberellic acid, 1-3 percent of 6-benayl aminopurine, 0.1-0.3 percent of alpha-rhodofix, 0.1-0.3 percent of forchlorfenuron, 0.01-0.02 percent of 24-epibrassinolide and 2.79-3.98 percent of tween 20. the agent for obtaining seedless graps can be prepared by adding the compounds into 90-95 percent of water or alcohol in the proportion and completely dissolving. spicae and fruit ears can be dipped with the agent 10-20 day before flowering and5 days and 10-20 days after flowering; and corresponding matched cultivating and managing technologies are carried out to obtain high-quality seedless grapes. The seedless agent for grapes can raise a seedless rate to 100 percent, and by using the agent, grapes have larger fruit and higher sugar content after being denuclearized, fruit keeping fresh period on plants can be prolonged, fruition rate is increased and the quantity of grapes is improved obviously, and social benefit is increased.

Description

technical field

[0001] The invention relates to a plant growth regulator, in particular to a regulator formula capable of making grapes seedless. Background technique

[0002] Grape seedless technology was first created in Japan in the 1950s. People treated grape flower spikes and young fruits with gibberellin to obtain seedless fruits and mature early. Since then, people at home and abroad have continued to test and research, and some non-nuclear agents have been used in production in China, such as: No. 1 and No. 2 grape non-nuclear agents from the Fruit Tree Institute of Jilin Academy of Agricultural Sciences; "Xiaoziling" from a research institute in Xinyang, Henan; "Mengwa I" from Yangling Dacheng Agricultural Technology Co., Ltd., Shaanxi; seedless agent for grapes from Yang Xiuwen, Liaoyang, Liaoning, etc. Although these technologies can basically make some varieties denuclearized (the denuclearization rate reaches more than 90%), and mature early, they all fail to s...
