Description

Technical Field

[0001] This invention belongs to the field of plant growth regulator technology, specifically relating to a plant growth regulator with glutenin as the active ingredient and its application. Background Technology

[0002] Plant growth regulators (PGRs) are a class of pesticides used to regulate plant growth and development. They include synthetically produced compounds with similar effects to natural plant hormones and natural plant hormones extracted from organisms. With arable land decreasing daily while the population continues to grow, coupled with frequent natural disasters, plant growth regulators are receiving increasing attention for ensuring food security and increasing yields. Traditional plant growth regulators suffer from high residue levels, significant pollution, poor safety profiles, and low utilization rates, failing to meet the needs of ecological agriculture. Therefore, developing new, multifunctional plant growth regulators is of great significance for increasing crop yields in my country and meeting the demands of a growing population.

[0003] Maltol, also known as maltin, is a plant growth regulator isolated from the metabolites of endophytic bacteria in rapeseed flowers. Maltin is a broad-spectrum flavor enhancer, commonly added to baked goods, desserts, and cosmetics, and widely used in the food, beverage, brewing, cosmetic, and pharmaceutical industries. Previous research in our laboratory has shown that maltol can be isolated from the metabolites of endophytic bacteria in rapeseed flowers. Currently, there are no reports of using maltol as a plant growth regulator in existing technologies. Therefore, if maltol can be formulated as an active ingredient to regulate the growth of grain crops, it will be of great significance. Summary of the Invention

[0004] In order to effectively regulate crop growth and development, this invention uses glutamic acid, which has plant growth-promoting properties and was previously isolated from the metabolites of endophytic bacteria in rapeseed, as an active ingredient to make a plant growth regulator, which is then used to regulate crop growth.
