摘要： 为了明确地衣芽孢杆菌对马铃薯晚疫病菌的抑制作用,研究了地衣芽孢杆菌对马铃薯晚疫病菌菌丝生长、游动孢子释放、游动孢子萌发、孢子囊萌发产生芽管的抑制作用.结果表明:地衣芽孢杆菌对马铃薯晚疫病菌的菌丝生长、游动孢子释放和游动孢子萌发有明显的抑制作用,对菌丝生长的抑制作用,抑菌带平均宽度达到5.58 mm,在稀释度为10-1时地衣芽孢杆菌对游动孢子释放的抑制率高达86.11%,对游动孢子萌发的抑制率也达到了78.1%.但地衣芽孢杆菌对马铃薯晚疫病菌的孢子囊萌发产生芽管抑制作用较弱.

Abstract: Inhibitory effects of Bacillus licheniformis against Phytophthora inf estans were tested at different stages.The results showed that B.lichenif ormis strongly inhibited the mycelia growth, release of zoospores from sporangia and germination of zoospores.The inhibitory rate to release of zoospores and germination of zoospores by B.lichenif ormis were 86. 11% and 78. 1% at dilution grade of 10-1.But to the germinat ion of sporangia of the the P.infestans inhibitory effect is not strong.
