紫外线辐照对猴头菌菌丝体生长的影响

Effects of UV Irradiation on the Mycelial Growth of Hericium Erinaceus

本文利用紫外线辐照猴头菌菌丝体，研究了不同辐照时间对猴头菌丝生长速度及生长势的影响.结果表明：紫外线辐照对其菌体的生长产生了不同程度的作用，辐照1～20min的处理组菌丝生长速度均高于对照组，其中辐照10min的处理组作用效果最显著，辐照超过20min却抑制了菌丝的生长；另外，在菌丝干重方面，辐照5～20min的处理组菌丝干重均高于对照组，其中辐照15min的处理组菌丝体干重最高为0.4581g.

In this paper,the UV irradiation of Hericium erinaceus mycelium is used for studying the effect of differ-ent irradiation time on the speed and growth rate of mycelial. The experimental results show that the growth of UV irradiation on Hericium erinaceus mycelium have varying degrees of role. The 10min irradi-ation treatment group and control group have significant difference,which promoted the growth of hyphae;the other group to handle the body dry weight of mycelia with 15 min irradiation was highest for the 0. 4581g.
