摘要
在大米培养基中添加蚕蛹粉,分析添加蚕蛹粉对蛹虫草菌丝体生长状况,子实体生长情况以及子实体有效成分虫草素、虫草多糖含量的影响。试验结果表明:蚕蛹粉添加量为6 g时,子实体生长状态最佳,畸形率最低、出草率最高、平均高度最高,干品产量最高,达到(5.36±0.087)g·瓶^(-1);在蚕蛹粉量为8 g时,虫草素与总虫草素的含量最高,分别达到(7.39±0.095)mg·g^(-1)和(34.06±0.164)mg·瓶^(-1);在蚕蛹粉量为6 g时,虫草多糖及总虫草多糖的含量最高,分别达到(23.26±0.086)mg·g^(-1)和(124.67±0.089)mg·瓶^(-1)。试验结果为蛹虫草产业化栽培及深层开发提供一定的理论依据。
The effect of silkworm pupa powder （SPP） on growth of Cordyceps militaris and active principle （ cordycepin and cordyceps polysaccharide） of sporocarp were anlyzed by adding SPP into the rice medium. The results showed that when the SPP amount was added by 6 g, the sporocarp grew best, with lowest deformity rate and highest average height, and the highest yield reached （5.36±0.087） g · bottle-1; while it was added by 8 g, the content of cordycepin and the total cordycepin is highest, reaching （7.39±0.095） mg · g-1 and （34.06＋0.164） mg· bottle-1 respectively; while it was added by 6 g, the content of cordyceps polysaccharide and total cordyceps polysaccharide was highest, reaching （23.26±0.086） mg ·g-1and （124.67±0.089） mg·bottle-1 respectively. This results would provide a reference for industrialization cultivation and deep development of C. militaris.
