Embodiment 1

[0097] Embodiment 1 mango tree top growth inhibitory effect test

[0098] Before the flower bud differentiation of mango trees, the plant growth regulating composition of the present invention is used to spray the whole fruit tree for 5-15 times in total, with an interval of 7-10 days between each time, and the germination inhibition rate at the top of mango branches is measured.

[0100]

[0101] The results show that the composition of the present invention has an obvious inhibitory effect on the top growth of mango trees.

Embodiment 2

[0102] Example 2 Inhibition Test of Flue-cured Tobacco Petiole Axillary Buds

[0103] Before the axillary buds of flue-cured tobacco petioles germinate, the plant growth regulating composition of the present invention is used to smear the petioles for 5-15 treatments in total, with an interval of 7-10 days between each time, and the germination inhibition rate is measured.

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...
