| 摘 要： | 从健康的11种植物体内分离到对辣椒疫霉Phytophthora capsici有强拮抗作用的两个内生细菌菌株,分别命名为LJ、XM菌株。拮抗试验表明,这两株细菌对多种植物病原真菌有较强的抑制作用。LJ和XM发酵滤液对辣椒疫霉病菌游动孢子囊的形成、孢子萌发均有较强的抑制活性。经LJ、XM发酵液处理的辣椒疫霉菌丝均有不同程度的原生质体浓缩现象。

| Abstract: | Two endophytic bacteria strains named as LJ and XM with strong antagonism against Phytophthora capsici were isolated from eleven different healthy plants.Both strain LJ and XM could suppress many plant pathogenic fungi.The fermentation filtrate of LJ and XM showed strong antagonistic activities to the zoosporangium formation and zoospore germination of Phytophthora capsici.The hypha of Phytophthora capsici treated with fermentation filtrate of LJ and XM showed different degrees of protoplast concentration. |
