Abstract: Solution-culture experiment was carried out to find out the proper application concerntration of zinc fertilizer.At the seedling stage,Licorice was treated with different Zn solution-culture concerntration.After 90 days,important indexes such as the yield,the contents of medicinal components,protein,anrino acids,total soluble sugar,and starches,the activities of nitrate reductase(NR),POD and SOD isoenzyme were determined.At the same time,the correlation of the yield and metabolic indexes was analysed.The result showed that under the concerntration of Zn at 0.1 μmol/L,the aboveground yield and every physiological index,the protein contents,and the contents of medicinal components of per plant as well as the activities of nitrate reductase(NR),POD and SOD isoenzyme of belowground were the highest.The correlation analysis was showed that there were certain correlation between the yield and some metabolic indexes.The concerntration of Zn at 0.1 μmol/L is the most suitable for Licorice growth and the accumulation of medicinal components.
