Effects of fermentation medium of Trichoderma aureoviride on growth and physiological characteristics of ryegrass
摘要
Abstract
Effects of different dilutions of the fermentation medium of Trichoderma aureoviride on growth and physio-logical characteristics of ryegrass were studied by seed germination and seedling pot experiment in vitro and pot experi -ments .Results showed that different dilutions of the fermentation medium of T .aureoviride can significantly increase the rates of seed germination ,germination index and vigor index ,especially for the dilutions of 100 times by which seed ger-mination rates ,germination index and vigor index were increased by 96 .55% ,37 .41 and 7 .83 ,respectively .Pot exper-iment results showed that different dilutions of the fermentation medium of T . aureoviride had obvious effects on the growth of ryegrass seedlings ,and can significantly increase the content of chlorophyll ,protein ,and defensive enzymes . Especially the dilutions of 100 times can increase ryegrass root length ,plant height ,fresh weight and dry weight by 16 .95% 、13 .33% 、40 .57% 、73 .68% ,and 36 .36% ,respectively .The content of chlorophyll and soluble protein were increased by 84 .09% and 75 .50% .Polyphenol oxidase ,peroxidase and phenylalanine enzyme activity were significantly higher than control after treatment with the dilutions of 100 times of T . aureoviride .Maximum activities of POD ,PPO and PAL were observed on 3 and 4 days after inoculation .Therefore ,the results suggested that the fermentation medium of T . aureoviride has substantial effects on growth and physiological characteristics of ryegrass .关键词
