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。
Ninety-nine endophytes were isolated from endophytic bacteria, including endophytic bacteria, 38 endophytic fungi, endophytic fungi, endophytic fungi, endophytic fungi, Actinomyces 8 strains. Fusarium oxysporum f.sp.cubense as target bacteria, isolated endophytic fungi antagonistic activity screening dishes and found endophytic fungi, endophytic actinomycetes antibacterial effect is not ideal endophytic bacteria YXG2 -3 antagonistic effect is the best, antibacterial zone up to 20mm, followed by BYG2-5, BYJ5-1, YXJ2-2. Four endophytic bacteria were tested in pot experiment and found that the strain YXG2-3 had the best control effect, reaching 63.8%, which reached extremely significant level with other treatments.
