蓝光诱导蛹虫草虫草素含量和分生孢子数的变化

目的]研究蓝光对蛹虫草菌丝体中虫草素含量和分生孢子量的影响。方法]以蛹虫草为材料,在不同的蓝光照射时间取样,以检测菌丝体中虫草素的含量,并计数蛹虫草分生孢子的产生量。结果]蛹虫草受蓝光照射后,其虫草素的产生受到了一定的抑制,同时虫草素含量的变化也有一定的波动性;在相同的时间点,受蓝光照射的蛹虫草分生孢子数量比黑暗时的分生孢子数量要多,同时在一定时间范围内分生孢子数均呈上升趋势。结论]该研究为系统性的研究蓝光对蛹虫草的影响奠定了基础。

Changes of Cordycepin Content and Conidia Amount of Cordyceps militaris by Blue Light Induction

Objective] The aim was to study the effects of blue light on cordycepin content and conidia amount of Cordyceps militaris mycelium. MethodI The cordycepin content of mycelium and amount of Cordyceps militaris conidia was detected at different blue light irradiation times by using Cordyceps militaris as materials. Result] The production of cordycepin was inhibited to a certain degree and the changes of cordycepin con- tent also had a certain fluctuation after the Cordyceps militaris was irradiated by blue light ; the amount of conidia of Cordyceps militaris irradiated by blue light was more than its number in the darkness at the same sampling time, and the number of conidia had been on an upward trend during a definite period of time at the same time. Conclusion] This study provided foundation for the system researches on the effects of blue light on Cordyceps militaris.
