- Abstract:
- Using seedlings of Festuca sinensis and Achnatherum inebrians as material，the effects of different dilutions of fermentation liquid of Epichlo isolated from F.sinensis on chlorophyll content，catalase，and peroxide dismutase were studied for providing theoretical and practical base for studying microbial fertilizers and pesticide by irrigating with stock solution，10 times，20 times，30 times，40 times and 50 times dilutions of fermentation liquid，respectively.The results indicated that different dilutions of fermentation liquid affected differently physiological indexes.20 times，30 times，40 times and 50 times dilution of fermentation liquid increased significantly chlorophyll a and total chlorophyll contents of F.sinensis seedlings (P＜0.05)，but stock solution decreased significantly chlorophyll b and total chlorophyll contents (P＜0.05).10 times，20 times，and 30 times dilutions stimulated significantly catalase activity (P＜0.05) with increasing 161.89%，104.76% and 47.95%，respectively，though 50 times dilution inhibited significantly catalase activity of F.sinensis (P＜0.05).Peroxide dismutase of F.sinensis treated with fermentation liquids were significantly higher compared with the control (P＜0.05)，with reaching 34.69%-95.92%.30 times，40 times and 50 times dilution significantly enhanced chlorophyll a，chlorophyll b and total chlorophyll contents of A.inebrians，with increasing 11.21%-26.17%，14.63%-26.22% and 13.65%-26.57%，respectively，though stock solution significantly reduced chlorophyll a，chlorophyll b and total chlorophyll contents.Catalase activity of A.inebrians treated with 10 times dilution were 15.14% higher than the control(P＜0.05)，but catalase activity of seedlings treated with other dilutions were significantly lower than the control(P＜0.05).Peroxide dismutase of A.inebrians treated with stock solution and 10 times dilution were significantly higher than the control(P＜0.05)，however peroxide dismutase decreased significantly by 30 times，40 times and 50 times dilution treatment(P＜0.05).
