The analysis of the phenomenon that the mushroom (Ganoderma lucidum) is controlled the mycelium growth by light irradiation.

本文研究了光照对灵芝菌丝体生长的影响。结果得到：在不同照度的光照射下，菌丝生长速率受光的波长和照度的影响，生长速率随光照度从亮状态切换到暗状态而变化。利用发光二极管光源和黑光检测波长对菌丝生长的影响，发现短波长（351470 nm）照射降低了菌丝生长速度。研究了光照对菌丝组分的影响。通过对菌丝体提取物的分析，可以看出β-1,3-葡聚糖含量和蛋白质组成等随光照条件的变化而变化。

In this study, the effect of li ght irradiation on mycelium growth of the mushroom (Ganoderma lucidum) was examined. As the result, the following s were obtained.When the light was irradiated at various illuminance, the mycelium growth rate was affected by wave length and the illumi nance of the light, and the growth rate followed the switching from lignt condition to dark condition of the optical illumination. It became clear that mycelium growth rate was lowered by the irradiation in short wavelength (351,470nm), when the effect of the light wavelength was examined using light emitting diode light source and black light.The effect of the light irradiation on the mycelium component s was also examined. From the analysis of the mycelium extracts, it became clear that β-1,3-glucan contents and protein compositions, etc. varied with the lighting condition.
