摘    要:将从香蕉土壤中分离出的7个不同性状的芽孢杆菌菌株以及荧光假单孢菌、枯草芽孢杆菌、细黄链霉菌等分别用于测试对香蕉枯萎病生理小种4号的拮抗作用。结果表明,10个菌株中荧光假单孢菌表现出对香蕉枯萎病生理小种4号菌丝生长有良好、稳定的抑制作用;荧光假单孢菌和XP菌株混合后,其抑菌作用得到加强,抑菌效果最好。

关 键 词:香蕉枯萎病菌  拮抗菌  拮抗作用

Abstract:Seven strains of Bacillus were isolated from the rhizosphere of banana.These isolates and one strain of Pseudomonas fluorescens,one strain of Bacillus subtilis,one strain of Streptomyces violaceusniger,were tested for their antagonistic effect towards the banana fusarium wilt pathogen,Fusarium oxysporum f.sp. cubense race 4 in vitro.Among the ten strains tested,P.fluorescens,B.subtilis,XP,BS,XFL showed good and steady effect in inhibiting the mycelial growth of Foc.race 4 and the mix of P.f.and XP was the most effective.
Keywords:Fusarium oxysporum f  sp  cubense  antagonistic bacterium  antagonism
