摘要
以实验室分离得到的枯草芽孢杆菌菌株LDB1为实验材料,通过对该菌株分别进行固体、液体培养条件下的抑菌谱比较研究,以明确该菌株对主要植物病原真菌的抑制效果。结果表明:(1)两种处理方式均对供试的8种植物病原真菌表现出较好的抑制效果;(2)除水稻纹枯病菌和苹果轮纹病菌外,LDB1菌株发酵液对其他6种病原菌的抑制作用皆比其固体状态强,Duncan多重比较分析显示,在α=0.05的水平上,两种处理方式差异显著。
In this study , the Bacillus subtilis strain LDB1 isolated by our laboratory was cultured under the condition of solid culture or liquid culture , and its antifungal spectrums to main plant pathogenic fungi were determined and compared .The results were as follows：（1） The strain LDB1 cultured under two different conditions all had obvious inhibitory effect on the tested 8 plant pathogenic fungi;（2） Except for Rhizoctonia solani and Physalospora piricola, the antifungal activity of LDB1 fermented suspension to other 6 plant pathogenic fungi was stronger than that of solid -state LDB1, and the significant （α=0.05） difference in the anti-fungal activity of LDB1 between two treatments was found by Duncan ’ s multiple comparison and analysis .
