【目的】从生防菌株产生的拮抗作用酶及生防菌株对病原菌生长的影响2方面研究黄绿木霉(YGF9)和木贼镰刀菌(LX6F2)对杨树溃疡病病菌葡萄座腔菌的抑菌机制,为杨树溃疡病的生物防治提供参考。【方法】通过生防菌株在几丁质培养基、纤维素培养基、β-l,3-葡聚糖培养基和酪蛋白培养基上的反应和生长情况,判定生防菌株能否产生几丁质酶、纤维素酶、β-1,3-葡聚糖酶和蛋白酶;通过显微镜观察2种生防菌株对病原菌菌丝生长和孢子萌发的影响。【结果】菌株YGF9和LX6F2代谢过程中均能使β-1,3-葡聚糖培养基中的蓝色消失,说明2种菌株具有产β-1,3-葡聚糖酶的能力;2种菌株可以在酪蛋白培养基上形成水解圈,说明...

Objective]Poplar canker is one of the major biological disaster of poplar plantations in China. Techniques of biological control to restrain poplar canker are sustainable and effective. Trichoderma aureoviride strain YGF9 and Fusarium equiseti strain LX6F2 are two biocontrol strains which were isolated from poplar tissue and soil,respectively. They may have the potential to prevent from and control poplar canker. In order to explore the mechanism of these strains in controlling disease, biocontrol efficacy of the strain YGF9 and the strain LX6F...
