Plant growth regulating composition with inhibiting plant tip growth function

Abstract

The invention relates to a plant growth regulating composition for top stress-resistance growth. It comprises A) a natural type abscisic acid B) ethephon C) 6-benzyl-amino-purine as active ingredient in addition of general inert auxiliaries. The compositions contain a weight ratio of A): B): C) of 1:0.01-300:0.01-100.Not only the cost can be reduced through plant growth regulating composition, but also with higher effect.

Description

technical field [0001] The present invention relates to a plant growth regulating composition containing natural abscisic acid, which has the effect of inhibiting the growth of plant tops. Background technique [0002] Natural abscisic acid, the common name of pesticides is S-abscisin (S-ABA), that is, (+)-cis, trans-natural abscisic acid, chemical name: 5-(1'-hydroxy-2',6',6 '-Trimethyl-4'-oxo-2'-cyclohexen-1'-yl)-3-methyl-2-cis-4-trans-pentadienoic acid, the structural formula is as follows: [0003] [0004] Natural abscisic acid (S-ABA), together with auxin, ethylene, gibberellin and cytokinin, is listed as the five major plant hormones. In 1963, natural abscisic acid was first extracted from cotton young fruit by Addicot et al. For more than 30 years, scientists from various countries have conducted extensive and in-depth research on the physiological activities of plants. The research shows that natural abscisic acid is the "stress-resistance inducing factor" of p...

Problems solved by technology

[0006] At present, the apical growth inhibitors commonly used in plant cultivation, such as paclobutrazol, ethephon, and dinozide, etc., but these agents also cause serious damage to plants while inhibiting apical growth, reducing the lifespan of plants. For example, paclobutrazol makes the trunk crack and sap , high concentration of ethephon caused severe lignification of the trunk, etc.
