| 摘 要： | 采用组织表面消毒法分离变叶木、益智、阴香、槟榔、椰子和菠萝蜜6种植物的内生菌,获得91株内生菌,其中内生细菌45株,内生真菌38株,内生放线菌8株。以香蕉枯萎病菌(Fusarium oxysporum f.sp.cubense)为靶标菌,对分离的内生菌株进行皿内拮抗活性筛选,发现内生真菌、内生放线菌抑菌效果不理想,内生细菌YXG2-3拮抗效果最好,抑菌带达20mm,其次是BYG2-5、BYJ5-1、YXJ2-2。对4株内生细菌进行盆栽试验,发现菌株YXG2-3防效最好,达到63.8%,与其他处理达极显著水平。

| Abstract: | Endophytic bacteria were isolated from Codiaeum variegatum,Alpinia oxyphylla,Cinnamomum burmannii, Areca catechu,Cocos nucifera,Artocarpus heterophyllus through surface disinfection method.91 endophytes were isolated,which included 38 endophytic fungi,45 endophytic bacteria and 8 endophytic actinomycetes. Antagonistic activity tried against Fusarium oxysporum f.sp.cubense.The results showed that:the inhibitory effect is not satisfactory about endophytic fungi and endophytic actinomycetes,the antagonistic ba... |
