| 摘 要： | 以感染霜霉病和健康的甘蓝叶片为试材,研究筛选了对甘蓝霜霉病菌有拮抗作用的内生细菌。结果表明:从健康的甘蓝幼苗中分离到18株内生细菌;用离体叶法进行测定,发现其中2株内生细菌对甘蓝霜霉病菌有拮抗作用,对其中一拮抗效果较好的菌株AC8进行田间防治试验,其防效达61.4%;通过形态观察、培养特征和生理生化特性鉴定,菌株AC8属于蜡状芽孢杆菌。

| Abstract: | Took the Leaves of cabbage as the material of the infected downy mildew and healthy,the selection of cabbage downy mildew had antagonistic endophytic bacteria were studied.The results showed that screen the endophytic bacteria antagonizing downy mildew of cabbage(Brassica olearcea L.var.capitata L.),18 strains of endophytic bacteria were isolated from healthy cabbage seedling in this study.The results showed that two strains can antagonize the downy mildew of cabbage.The strain of EC8 with better antagonist... |
