摘要:
通过筛选出对植物土传疾病具有良好拮抗效果的菌株BS-17,对其生防效果进行测定,旨在为开发植物土传疾病广谱抗菌生物制剂提供一定依据。采用平板对峙法,筛选出对9种常见植物土传疾病具有拮抗效果的拮抗菌,抑菌率均在80%以上。利用形态学、生理生化及分子生物学的方法对其进行了鉴定,并对拮抗物质产生的位置以及性质进行初步研究;通过土壤定殖试验对其生防潜力作出评价。通过形态学、生理生化及分子生物学的方法鉴定菌株BS-17为解淀粉芽孢杆菌(Bacillus amyloliquefaciens)。该菌产生的主要抗菌物质分布于胞外,拮抗物质对热、pH值、紫外线以及蛋白酶均不敏感。此外,菌株BS-17具有较好的产纤维素酶及蛋白酶的能力。土壤定殖试验证明,该菌表现出良好的定殖能力以及抑制病原菌生长的能力。菌株BS-17作为生防菌用于防治植物土传疾病,具有较好的开发和利用价值。
