球孢白僵菌孢子的耐逆性研究

The Research on Spores Inverse Resistance of Beauveria Bassiana

测定了温度、pH、紫外线照射对D1-5球孢白僵菌在极性条件下对孢子萌发的影响,并找到萌发最适条件.实验结果表明：在其他条件相等时,温度在15~40℃都能萌发,19~28℃为最适应温度.球孢白僵菌孢子在pH 3~11之间都能萌发,萌发率在pH≤7时随着pH增大而升高,在等于7时达到峰值95.06%,而后逐渐下降.紫外线照射会严重影响球孢白僵菌的孢子萌发.

Measured the temperature, pH, ultraviolet radiation on the D1 -5 Beauveria bassiana under the condition of polarity effect on the spore germination, the germination optimum conditions are found. The experimental results show that ：when the other conditions are equal, Beauveria bassiana can germination at 15 to 40 ℃. 19 to 28 ℃ is the preference temperature, beauveria bassiana spore germination between pH 3 11, germination rate at pH 7 or less with the increment of pH,in the 7 is equal to the peak of 95.06% , and then gradually decline. Ultraviolet radiation will seriously affect the Beauveria bassiana spore germination.
