AI Technical Summary

Technical Problem

No studies in the prior art have disclosed the mechanism of action of uniconazole and aminoethyl ester in Ginkgo biloba, and they have failed to effectively regulate the growth of Ginkgo seedling height, diameter at root, biomass, and metabolite accumulation.

Method used

The growth and metabolite accumulation of Ginkgo seedlings were regulated by spraying with different concentrations of uniconazole and aminoethyl ester. Specific measures included treating Ginkgo seedlings with different concentrations of uniconazole and aminoethyl ester to regulate the growth of seedling height, diameter at root, biomass, and the content of metabolites such as chlorophyll, soluble protein, soluble sugar, and total flavonoids.

Benefits of technology

It effectively controlled the height, diameter at root, and biomass of ginkgo seedlings, increased the content of metabolites such as chlorophyll, soluble protein, soluble sugar, and total flavonoids, and optimized the growth and metabolite accumulation of ginkgo.

Abstract

The application of uniconazole and alminotran in regulating the growth and metabolite accumulation of ginkgo biloba is disclosed, and relates to the technical field of plant growth promotion. The application of uniconazole and alminotran in regulating the growth and metabolite accumulation of ginkgo biloba is disclosed, and takes 2-year-old ginkgo biloba seedlings as materials, and applies 30-60 mg / L uniconazole or 50-200 mg / L concentration of alminotran, and the best uniconazole and alminotran concentrations for promoting the growth of ginkgo biloba, increasing the chlorophyll content, increasing the primary metabolite activity and increasing the secondary metabolite content are 50 mg / L and 100 mg / L respectively. Taking 3-year-old grafted ginkgo biloba seedlings as materials, the comprehensive indexes of ginkgo biloba leaves are best after 25 d of spraying 50 mg / L uniconazole and 100 mg / L alminotran.
