摘要:
在比较枯草芽孢杆菌NH-8及其突变体B2、H7抑菌活性的基础上,以苏粉8号番茄幼苗为试材,比较枯草芽孢杆菌NH-8及其高效突变体对番茄幼苗生长、抗性酶活性的影响。结果表明,NH-8菌株及其高效突变菌株对番茄生长具有明显的促进作用,接种H7菌株的番茄幼苗其幼苗株高、主茎高度、鲜质量、干质量分别为42.50 cm、282 cm、1498 g/株、4.65 g/株,较清水对照增加73.04%、276.00%、77.28%、100.43%;2个高效突变菌株的拮抗能力较枯草芽孢杆菌NH-8有所提高,其促生作用和诱导抗性酶活性大多相应增强;接种生防菌株H7的番茄叶片过氧化物酶、超氧化物歧化酶、过氧化氢酶、多酚氧化酶活性相对最大,分别为4.5、55.5、47.6、14.7 U。
