防治紫花苜蓿真菌病害的生防菌筛选
Screening of inhibitory bacteria for prevention and treatment of fungal diseases of Medicago sativa
摘要
Abstract
The inhibitory effect of two bacteria on 9 alfalfa pathogens were tested on PDA medium using the confrontation method;the taxonomic status of each pathogen species were determined using morphological and molecular criteria.The bacteria identified were Bacillus amyloliquefaciens and Streptomyces kanamycin.The inhibitory effect of Bacillus amyloliquefaciens ranged from 24.02%-71.11%,with the greatest effect shown against Cercospora medicaginis (71.11%),Stemphylium botryosum (64.76%) and Fusarium roseum (60.55%).The inhibitory range of Streptomyces kanamycin was similar (49.95%-76.90%) with greatest effect against Colletotrichum trifolii (76.90%),Phoma medicaginis (70.94%),Stem ph ylium botryosum (68.01 %) and Leptosphaerulina briosiana (60.99 %).Bacillus amyloliquefaciens and Streptomyces kanamycin showed varying degrees of antagonism to different alfalfa pathogenic fungi indicate that they have promise as biological control agents for a variety of Medicago sativa foliar diseases,suggesting further development should be undertaken.关键词
