Abstract
Dormant sporangiospores of Phycomyces blakesleeanus were activated by Cs-137 gamma rays. After a dose of about 300 krad, between 80 and 90% of the spores germinated normally. However, further development of the mycelium was inhibited. Even with dry spores a partial activation was obtained. Activation by gamma rays was not accompanied by an increase in trehalase activity.
摘要
黑根霉的休眠孢子囊孢子可被铯 - 137γ射线激活。在约300千拉德的剂量后，80%至90%的孢子能正常萌发。然而，菌丝体的进一步生长受到抑制。即使是干孢子也能实现部分激活。γ射线激活并未伴随着海藻糖酶活性的增加。
