Selection of Beneficial Endophytic Bacteria for Biological Control of Wheat Sharp Eyespot
摘要
Abstract
A total of 296 endophytic bacterium strains were isolated from 38 samples of healthy wheat roots collected from western area of Henan province. In vivo tests were used to acquire efficient biocon-trol strains against wheat sharp eyespot and the results showed that 13 strains could reduce significantly the incidence and severity of wheat sharp eyespot. Among endophytic bacteria isolates, strain Z8 - 15 had the best biocontrol efficacy against wheat sharp eyespot, reaching 81. 82%. Antagonistic activities against Rhizoctonia cereali and Gaeumannomyces graminis var. Tritici, and abilities to produce fungi cell wall degradation enzymes such as glucanase, chitinase, proteinase, etc, of 13 endophytic bacteria were tested on plate. The results of obvious difference between strains indicated that different biocontrol mechanisms existed among different endophytic bacteria.关键词
