Seed Coating Formulation Research Of Glycyrrhizae

The dried roots and rhizomes of Glycyrrhizae（Glycyrrhiza uralensis Fisch.）、Glycyrrhizainflata（Glycyrrhiza inflatable Bat.）Or Glycyrrhiza glabra (Glycyrrhiza glabra L.) is aleguminous plant of the genus Glycyrrhizic,Ningxia and Gansu provinces of northwest is thelargest production,Research on one of the extremely valuable of medicinal plants over theyears.The main problem of Glycyrrhizae for of medicinal plants cultivated in growthhabit,Developed the seed coating formulation of Glycyrrhizae,seed coating formulation ofGlycyrrhizae of physicochemical properties were determined, Research on the effect ofmorphological indicators, physiological indicators of the impact of seed coating formulation ofGlycyrrhizae and the content of Glycyrrhizic acid.The results show that seed coating formulation of Glycyrrhizae in coating technique withrelated experimental treatment, seed coating formulation in the effect of morphologicalindicators, physiological indicators and the content of Glycyrrhizic acid were produced differentdegrees of impact, The main conclusions are:1、Seed coating formulation of Glycyrrhizae of preparation process is simple, seed coatingformulation of the physical and chemical properties and in full compliance with nationaltechnical standards in general.2、After the use of seed coating formulation of Glycyrrhizae of coating technique deal withrelated experimental, can improve germination potential and germination rate of Glycyrrhizicseed.3、Seed coating formulation of Glycyrrhizae can improve the the height to a certain extent,Increased root diameter, stem diameter, so that the root dry weight, stem dry weight, leaf dryweight improved, root volume of Glycyrrhizae increases, and to increase and improveglycyrrhizic leaf area index of seedling, in favor of growing period of morphogenesis ofGlycyrrhizae.4、Seed coating formulation of Glycyrrhizae can improve root the activity of Glycyrrhizae,the content of chlorophyll, the content of nitrate, the content of protein and the content ofsoluble sugar. Description, can enhance the ability to use root to absorb water, of minerals andnitrogen in soil; improve photosynthesis of Glycyrrhizae, accelerate metabolism, promote thesynthesis and transformation of proteins and carbohydrates. Thereby providing more materialand energy for the growth and development of Glycyrrhizae, and promote the growth anddevelopment of Glycyrrhizae. 5、Glycyrrhizic acid is an important active ingredients of Glycyrrhizae,the content ofGlycyrrhizic acid is an important indicator of the level of quality, Research on that seedcoating formulation of Glycyrrhizae can improve the content of Glycyrrhizic acid in annual,So that improved the quality of Glycyrrhizae, improve the medicinal value of Glycyrrhizae.
