光条件对人工培养蛹虫草子座产量及虫草素和腺苷的影响
Effect of Light Conditions on Growth of Cordyceps militaris and Mass Fraction of Cordycepin and Adenosine

以蛹虫草菌株CM-16为研究对象，小麦为主要栽培基质，研究不同的光条件对蛹虫草的子座产量及虫草素和腺苷的影响。结果表明，当光照度为150 lx时，子座产量及2种有效成分质量分数均较高，此时子座产量（以干质量计）达到每盒52.66 g，虫草素和腺苷的质量分数分别为4.56 mg/g和2.11 mg/g；光照时间为8 h/d 时，子座产量及虫草素质量分数较高，此时子座产量达到每盒54.30 g，虫草素质量分数为4.41 mg/g，光照时间对腺苷的积累影响不大；蓝光有利于蛹虫草生长和子座积累虫草素，但其他光质对子座中的腺苷的作用没有太大差异。
Growth of Cordyceps militaris CM-16 and changes of two active ingredients (cordycepin and adenosine) were studied in wheat medium under different light conditions. The results showed that when illumination intensity was 150 lx, the production of stroma, cordycepin and adenosine reached to the maximum, 52.66 g/box, 4.56 mg/g and 2.11 mg/g respectively. When illumination time was 8 h/d, the production of stroma and content of cordycepin were the highest, 54.30 g/box and 4.41 mg/g respectively. But illumination time had less effect on the accumulation of adenosine in stroma. Blue light were benefit for the growth of Cordyceps militaris and cordycepin accumulation, however, Blue light had no significant difference on the content of adenosine compared with other light wave.
