摘要
研究环境因子对莱氏野村菌（Nomuraearileyi）cq菌株的生长、产孢与孢子萌发的影响。温度对菌株的生长、产孢和孢子萌发有相同的效应，低温23℃是最适温度，32℃以上明显抑制谊菌的生长、产孢和孢子萌发；最适宜生长、产孢和孢子萌发的pH范围为6．2～7．0；24h光照有利于产孢，而24h黑暗有利于菌落生长；紫外线（40w，45cm）照射2min，培养96h谊菌株孢子发芽率较对照降低16％，照射8min孢子发芽率仅为7％。
An experiment with eq strain of Nomuraea rileyi, an entomopathogenic fungus isolated from silkworm （Bombyx mori）, in laboratory showed that a lower temperature of 23℃ was optimum for the growth, sporulation and germination of the fungus while higher temperature （≥32℃） inhibited its growth, sporulation and germination. The favorable pH for its growth, sporulation and germination ranged from 6.2 to 7.0. A photoperiod of 24 h light promoted sporulation and a photoperiod of 24 h darkness favored the growth of the colony. With UV-light （40 W, 45 cm） irradiation for 2 min reduced its spore germination rate by 16% as compared with the control. 95% of the spores had a germination rate as low as 7% when they were irradiated with UV-light for 8 min.
