几种表面活性剂及营养物对虫生真菌孢子萌发的影响
0
()
摘要:
研究了球孢白僵菌、金龟录僵菌和粉拟青霉在吐温-80及6种不同的洗衣粉中的分散性及活力。结果表明,3种真菌在这些表面活性剂中的分散指数差异不显著。白僵、绿僵不同浓度的吐温-80液中的发芽同于不加表面活性剂的对照。多数洗衣粉显著抑制3种真菌的萌发,但白僵菌在0.1%和0.05%白猫牌无泡超浓缩洗衣粉中发芽 对照差异不显著,在5%和2%葡萄糖液,2%和1%蛋白胨液中,白僵菌孢子在发者发育率最高。

Impact of Some Surfactants and Nutritions on Conidial Germination of Entomogenous Fungi
()
Abstract:
In the present stutly,the dispersality,viability(in terms of germination)ofthe conidia of Beauveria bassiana,Melarhizium anisopliae,and Paecilomyces farinosus in dif-ferent concentrations of Tween-80 and 6 common commercial powder detergents,The re-sults showed that the difference of dispersal indices of the conidia of the 3 fungi in these sur-factants was not significant.The germination rates in different concentrations of Tween-80 of B.bassiana and M. anisopliae were mostly higher than in control not treated in any surfactant with an exception of M,anisopliae in 0.2% Tween-80 lower than control.Al-most all detergents inhibited the germination significantly except B, bassiana in low concen- tration of one detergent.Conidia of B. bassiana in 5 liquid media,5% and 2% glucose,2%and 1% peptone,and 2% glucose pius 1% peptone resulted in the highest germination ofthe 3 fungi.
