摘　　要：以香蕉炭疽病拮抗菌C71菌株为出发菌株,通过紫外诱变、对峙培养筛选,获得106株拮抗活性增强的菌株;通过遗传稳定性测试、培养滤液对香蕉炭疽病菌的抑制作用及对香蕉采后炭疽病的防效测定,获得了4株比出发菌株C71拮抗性能、防病能力、稳定性更好的优良菌株。The antagonistic bacterium strain C71 against banana anthracnose was mutated by UV light and then screened by pairing culture on PDA, and 106 strains from the inhibition zone were obtained. Of these strains, 4 remained stable after 20 times of subculture, improved inhibition rate against C. musae and enhanced the controlling effect against banana anthracnose as compared to the strain C71.
