海洋细菌L1-9菌株对小麦的促生防病作用研究
Contro1 Efficacy and Growth-promoting Ability of Marine Bacterium Strain L1-9 in Wheat
摘要
Abstract
Antimicrobial activities of marine bacterium L1-9 strain against Bipolaris sorokiniana and Fusarium gramin,-earum were detected through dual culture and agar-well diffusion method. Results showed that the fermentation broth and culture filtrate of strain L1-9 was obviously inhibitory to mycelial growth and conidia sporulation of the two pathogenic fungi . Seed germination test and pot experiment demonstrated that after wheat seeds were soaked into the fermentation broth and culture filtrate of strain L1-9, respectively, the germination rate, germinating potential, seedlings rate, plant height, net weight and root length were all increased remarkably, and the growth of wheat seedling was promoted. The fermentation broth and culture filtrate of strain L1-9 exhibited good inhibitory effect on B. Sorokiniana and F. Granrineanan. Furthermore, the inhibitory effect of fermentation broth was better than that of culture filtrate, with control efficacy of 82% and 73.84%, respectively.关键词
