烟色离褶伞基内菌丝生长规律及生产中的应用

烟色离褶伞基内菌丝自接种点向PDA培养基内延伸的生长距离最长为1.5 cm,但足以布满18 mm×180 mm PDA斜面试管基内各个角落.基内菌丝继代转接的原种菌丝较气生菌丝继代转接的原种生长快、菌丝茁壮,但在产量上没有显著差异.通过对基内菌丝生长规律的观察,发现了食用菌母种再生千倍转接技术,使其扩展应用到食用菌生产中,为进一步改进食用菌生产程序、缩短生产时间提供理论基础.

Substrate Hyphae Growth Rhythm of Lyophyllum fumosum and Application in Mushroom Production

Substrate hyphae of Lyophyllum fumosum reached the ultimate limit distance in PDA slant test-tube medium was 1.5 cm, which could extend in the different parts of 18 mm×180 mm PDA slant test-tube medium. Spawn of substrate hyphae successive transfer culture grew faster and stocky than that of aerial hyphae. However, it was no significant difference in the yield. In this studies the thousand-fold translation technology of mother spawn regeneration were discovered, and this technology could be introduced into mushroom production, which could provide theoretical basis on improving process of mushroom production and shortening production cycle.
