Problems solved by technology

A single plant growth regulator has a relatively single effect on promoting the growth of crops, and the compounding of plant growth regulators with different mechanisms of action can effectively solve this problem
The active ingredient A and active ingredient B of this application have different action mechanisms, and their mutual compounding has a good synergistic effect within a certain range. The binary compounding of methylglutaric acid, mepiperium, and choline chloride has not been reported at home and abroad.

Abstract

The invention relates to a plant growth regulating composition containing jasmonic acid and methyl jasmonate. The plant growth regulating composition contains an active component A and an active component B, wherein the active component A is jasmonic acid or methyl jasmonate, and the active component B is any one selected from a group consisting of benzyl aminopurine, forchlorfenuron, ethephon, tetramethyl glutarate, mepiquat chloride and choline chloride. The plant growth regulating composition is mainly used for improving enzyme activity, promoting seed germination, enhancing germination capacity and photosynthetic intensity, increasing the content of chlorophyll, maintaining greenness, preventing ageing, promoting development of roots and effective fertilizer absorption of crops, assisting the inferior part of a crop in good growth, enhancing absorption of water and fertilizer by plants and adjusting the balance of moisture in plants so as to improve drought resistance and cold resistance of plants; and the plant growth regulating composition can improve immunity, disease and insect resistance and crop quality and increase yield and income.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a plant growth regulating composition containing jasmonic acid and methyl jasmonate in crops. [0002] technical background [0003] Jasmonic acid (jasmonic acid, referred to as JA) chemical name: 3-oxo-2-2'-cis-pentenyl-cyclopentane-1-acetic acid, and jasmonic acid methyl ester (abbreviated as JA_Me), is a kind of fatty acid Derivatives, endogenous growth regulator substances present in higher plants. Jasmonic acid is a hormone that is ubiquitous in various plants and has a wide range of physiological functions. It is currently considered as an endogenous growth regulator in higher plants. More importantly, it is a signal molecule that induces the expression of plant defense genes by pathogens, elicitors and wounding, and it can also act as an elicitor itself. A large amount of genetic and molecular biological evidence has shown that JA, as an important endo...
