摘  要:
采用盐酸和甲醇抽提法,提取了枯草芽孢杆菌XF-1(Bacillus subtilis XF-1)的抑菌物质。以该提取物处理根肿菌孢子2 d,有50%孢子活性被抑制;处理9 d后,孢子萌发相对抑制率始终保持在90%以上。提取物对三七根腐病菌、水稻纹枯病菌、禾谷镰刀菌、魔芋基腐菌、烟草赤星菌生长抑制率分别为71.97%、62.23%、60.96%、60.70%和57.92%。

Bacillus subtilis XF-1;Plasmodiophora brassicae;antagonistic substance;inhibition effect
摘  要:
The antagonistic substance,isolated from the culture of Bacillus subtilis XF-1 by a method of hy-drochloric acid precipitation conbined with methanol extraction substance,could inhibit 50% resting spore activity of Plasmodiophora brassicae treated for 2 d and over 90% spore germination treated for 9 d.The inhibition rates were 71.97%,62.23%,60.96%,60.70% and 57.92% of the plant pathogens,i.e.Fusarium solani,Rhizoctonia solani,F.graminearum,F.solani,and Alternaria alternate,respectively.
