Effect of Fermentation Liquid of Epichlo(e) Isolated from Festuca sinensis on Seed Germination
Effects of different dilutions of fermentation liquid of Epichlo(e) isolated from Festuca sinensis on germination potential,germination rate,seedling length,root length and seedling fresh quality of F.sinensis and Achnatherum inebrians seeds were studied by soaking 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 growth indexes.40 times dilution of fermentation liquid increased significantly germination potential and germination rate of F.sinensis seeds (P ＜ 0.05),but others significantly inhibited germination potential and germination rate (P ＜ 0.05).10 times,20 times,30 times,and 40 times dilutions stimulated significandy seedling growth (P ＜ 0.05),though stock solution inhibited significantly seedling growth of F.sinensis (P ＜ 0.05).Root length of F.sinensis treated with stock solution and 20 times dilution were significantly lower compared with the control (P ＜ 0.05).10 times dilution significantly enhanced seedling fresh quality,but 40 times and 50 times dilution significantly reduced seedling fresh quality of F.sinensis (P ＜ 0.05).Germination potential of A.inebrians treated with 10 times or 50 times dilution were significantly greater than the control seeds (P ＜ 0.05),and germination rate of seeds treated with 10 times dilution were significantly higher than the control (P ＜ 0.05),but germination potential and germination rate of seeds treated with stock solution was significantly lower than the control(P＜ 0.05).20 times and 30 times dilution elevated greatly seedling length of A.irebrians (P ＜ 0.05),however seedling length decreased significantly by 40 times and 50 times dilution treatment when compared with control.Root length in stock solution and 30 times dilution-treated samples were significantly lower than the control (P ＜ 0.05).There were marked seedling fresh quality increases in seedling of A.inebrians treated with stock solution and 10 times dilution compared with the control (P ＜ 0.05).
