【摘要】 研究了不同的温度、湿度、光照、pH值、碳源、氮源、微量元素等条件对木霉菌Tr01菌株孢子萌发影响作用。结果表明:25￣30℃及高湿环境是木霉菌Tr01菌株分生孢子萌发的适宜温湿度条件,光照对孢子萌发无影响;分生孢子在pH值6￣5的弱酸环境下萌发最好;碳源中,麦芽糖能极大地促进孢子萌发,蔗糖、葡萄糖对孢子萌发具有一定的促进作用;有机氮源的蛋白胨对孢子萌发具有极大促进作用,无机氮源中NH4Cl、NH4NO3也能较好地促进孢子萌发,KNO3、NaNO3等则对萌发无促进作用;微量元素中一定浓度的MnSO4.4H2O、ZnSO4.7H2O能够明显地促进孢子萌发。更多还原

【Abstract】 The results showed that the optimal conditions for spore germination were the 25-30℃,high moisture level and pH at 5-6.The illumination has no effect on spore germination.Maltose strongly promotes germination of the conidia compared with glucose and sugar.In addition,peptone mereased the percentage of conidia germination.In the inorganic nitrogen sources,NH4NO3 and NH4Cl could improve conidia germination.Among different trace elements,MnSO4·4H2O and ZnSO4·7H2O could stimulate germination of conidia.更多还原
