在凤尾菇组织分离及母种继代扩大培养中,经常出现菌丝纽结,甚至在接种点处产生子实幼体(具菌盖、柄)的现象,致使菌丝活力下降,影响菌种质量,仅十来天菌龄的母种成批报废。究竟管内子实体形成的主导因素是什么?我们作了以下试验。供试菌种系1981年初从广东微生物所引进的凤尾菇(Ple urotus sajor-caju P_(10))组培材料。采用PDA改良培养基,分装于20×200mm试管中,常规
In the separation of Pleurotus ostreatus and its parental expansion, the mycelial kyphosis often occurs, and even the phenomenon of producing juvenile larvae (with cap and handle) at the point of inoculation results in the decrease of mycelium vitality, Quality, only ten days of age of the mother batch rejection. What is the dominant factor in the formation of in-tube sub-entities? We made the following test. The test strains were Pleurotus sajor-caju P_ (10) introduced from Guangdong microorganisms in early 1981. PDA modified medium, sub-installed in 20 × 200mm tube, routine
