摘要
蛹虫草(Cordyceps militaris)属冬虫夏草的同属异种真菌,在蛹虫草菌丝、子实体等不同部位均含有多种活性成份,具有较高的经济价值,可食、药兼用。在栽培中,容易出现菌株退化,导致出草率下降甚至不出草,有效活性成份降低,对产业发展造成不良影响,研究蛹虫草菌株退化的表型特征与退化机制,可为生产中甄别退化菌株提供理论依据,采取合理方法进行菌株复壮,可有效降低生产风险。
Cordyceps militaris is a congener and heterologous fungus of Cordyceps militaris,which contains a variety of active ingredients in different parts of Cordyceps militaris,such as mycelia and fruiting body,which has high economic value and can be used as both food and medicine.In the cultivation process,it is easy to appear strain degradation,resulting in a decrease production of fruiting body or even no production and lower active ingredients,which has a negative impact on the industrial development.Research the phenotypic characteristics and degradation mechanism of Cordyceps militaris strain degradation can provide the theoretical basis for identifying degradation strains in production and adopt reasonable methods for strain rejuvenation,so as to reduce production risks.
