摘　　要：通过测定菌落生长速度和孢子萌发率对绿僵菌菌株JF-813抗逆性进行了研究，结果表明：菌株JF-813有较强的抗逆性，在pH值4～9范围内的PPDA培养基（添加1％蛋白胨的PDA培养基）中均可以生长，其最适pH值为8；在NaCl浓度为0．05—0．25mol／L条件下，NaCl对菌株JF-813的生长有一定的促进作用，浓度越大促进越明显，该菌株有较强的耐盐能力；高温条件及紫外光对绿僵菌菌株JF-813孢子萌发有较强的抑制作用。The research focused on stress resistance of Metarhizium sp. strain JF-813 by measuring colony growth rate and spore germination rate. The results showed that this strain JF-813 could grow on PPDA medium （PDA medium supplemented with 1% peptone） with pH range of 4 to 9 and the most suitable pH was 8. NaC1 at a concentration of 0.05 O. 25 mol/L in the substrate could increase the growth significantly and the tests indicated that the strain was able to endure saline. High temperature and UV lihgt inhibited the conidial germination of the stain JF-813.
