Biological Characteristics of the Pathogen of Schisandra chinensis Leaf Blight and Screening of Antagonistic Actinomycete Strain against the Pathogen
摘要
Abstract
Petri dish culture method was used to study biological characteristics of Schisandra chinensis leaf blight pathogen, and plate confrontation method was used to screen antagonistic actino⁃mycetes. The results showed that mycelia grew faster and spore generated more in medium PDA and PDBA. Temperature affected mycelia growth and spore generation at 25 ℃. At the same tempera⁃ture, dark condition was significantly beneficial for spore generation and light condition was benefi⁃cial for mycelial growth. pH 6~7 was most suitable for the pathogen. Fructose and peptone were the best carbon source and nitrogen source for the pathogen. Deadly temperature for the spore was 54 ℃. Two strains ( A-25-8 and A38 ) of the 28 actinomycetes had potential antagonistic effects against leaf blight pathogen and inhibition rate was 66�26% and 66�10%, respectively.关键词
