[0034] Sleep Breaker Test - Edible Grapes

[0035] This experiment is a grape branch dormancy test conducted under greenhouse conditions. It adopts the international general method and uses a thermal energy detection recorder to collect and analyze the heat energy accumulation generated by grape axillary buds during dormancy, so as to judge the dormancy effect.

Abstract

The invention discloses an application of brassinolide, a method for breaking dormancy of fruit trees in advance, a dormancy breaking agent and an application. The invention provides the application of the brassinolide in breaking of dormancy of the fruit trees, and the brassinolide is 24-epibrassinolide; during use, the brassinolide is the unique active ingredient, the use concentration is 0.05-1ppm, and the use method of the brassinolide is that the brassinolide is used once during complete dormancy of the fruit trees. The invention also provides the dormancy breaking agent taking the brassinolide as the unique active ingredient and an application of the dormancy breaking agent in breaking of dormancy of fruit trees. The dormancy breaking agent has the benefits that the dosage of the brassinolide is very low, no environment residue problem is caused, and the dormancy breaking is safe and effective.

Description

technical field [0001] The invention relates to an application of brassinolide, a method for breaking sleep of fruit trees in advance, a sleep breaking agent and application thereof. Background technique [0002] In the process of growth and development, deciduous fruit trees go through the stages of germination, leaf growth, flowering and fruiting, and then enter the winter dormant period. The climate warms up in the coming year, and a new round of growth stage begins. This is the natural growth phenomenon of deciduous fruit trees. . However, in many winter-free areas and warm winter climates, the low temperature conditions required for fruit tree dormancy are insufficient, and the fruit trees do not germinate or the germination time is uneven, which makes the flowering and fruiting time correspondingly prolonged. For fruit farmers, this situation is not conducive to On the other hand, in the planting management of orchards, the ripening time of fruits is inconsistent, and...
