| 摘 要： | 抗逆性测定结果表明,淡紫拟青霉PL04菌株有较强的抗逆性和对化学农药的兼容性.PL04菌株在PSA培养基上菌落生长和产孢的适温为5～40℃ (最适温度为29℃). PL04菌株在pH4～13(最适pH为7)范围内的培养基上均可生长;PL04菌株在40℃和50℃条件下的LT50分别为78.8 min和40.8 min.PL04菌株有较强的耐盐碱能力;PL04菌株对氯霉素有较强的耐受性;PL04菌株对杀菌剂多菌灵、百菌清、苯醚甲环唑、除草剂百草枯以及消毒防腐剂福尔马林较敏感,其EC50分别为0.021、0.013、0.006、0.016和0.120 mg/mL,PL04菌株对杀线虫剂阿维菌素和辛硫磷,杀菌剂三唑酮不敏感,其EC50分别为0.175 、0.338和0.337 mg/mL.采用双温测定法,室内测定淡紫拟青霉PL04菌株对香蕉根结线虫的寄生作用,不同处理具有显著性差异,PL04菌株孢子悬浮液处理18 d后对香蕉根结线虫卵的相对寄生率为94.3%.
