Comparison of quality and yield of different genotype Glycyrrhiza uralensis

A culture experiment was conducted to compare the quality and yield of different genotype Glycyrrhiza uralensis for selecting the fine licorice lines of G. uralensis by measuring the biomass, glycyrrhizic acid contents, flavoniods, polysaccharide, soluble sugars, amino acid and protein. This study showed that the yield and the glycyrrhizic acid content of the strains with good quality and high yield were 3 and 1.6 times that of the strains with poor quality and low yield, respectively. The comprehensive analysis showed that the plant height was not correlative relationship with the quality and stem color, while the yields of highgreen plants were higher than that of lowpurple ones.
