Effect of Bacillus on Growth and Quality Markers of Corydalis yanhusuo
Objective To study the effect of Bacillus on the growth,physiological and biochemical indicators,quality markers of Corydalis yanhusuo.Methods Using bacillus subtilis,bacillus laterosporus,bacillus glia and three kinds of mixed bacillus micro-bial inoculum treated Corydalis yanhusuo which planted in flowerpots,non-inoculation was used as a control.The growth index,physiological and biochemical parameters of leaves were determined during the growth period,and the amount of quality markers was determined by HPLC after harvest.Results The results showed that the four bacterial treatments significantly improved the growth indexes of Corydalis yanhusuo,bacillus laterosporus significantly increased the activity of antioxidant enzymes;the four treatments had no significant effects on malondialdehyde and soluble sugar content,but all of them significantly increased the solu-ble protein content;except for bacillus glia,the other three treatments significantly increased the content of four alkaloids.Con-clusion Application microbial inoculum of bacillus laterosporus and bacillus subtilis,can improve the yield and quality of Coryda-lis yanhusuo.
