单核菌丝

杂交试验表明，出发菌株IM02、突变株A1与金针菇单核菌丝IS02均形成了锁状联合。碘液染色检查发现绝大多数花粉不育，并与该突变株的低结实率一致。

The authenticity of the mutant strain was confirmed by the hybridation test . When staining with iodic solution , most of the pollens showed sterility , which was in consistence with the low setting percentage of the mutant plant .

以及菌褶子实层、单核菌丝、双核菌丝中的丝状菌丝、粉状菌丝和产孢菌丝团的显微构造；

The microstructure of the lamella hymenia , spore-bearing mycelia , the filaments and " powdery " hyphae of the uninucleate and dicaryophytic hyphae were also described in detail .

单核原生质体再生菌丝的菌落形态、菌丝生长速度和营养缺陷型标记等性状均稳定地保持了亲本的特性。

The characters of parents , such as morphology of colony , growth rate of mycelium and auxotroph , were maintained in protoplasted monokaryon .

经测定，单核原生质体再生菌丝杂交后代菌丝生长速度和羧甲基纤维素酶活性的广义遗传力分别为61.0%和88.8%。

The broad-sense heritability of mycelium growth rate and cellulase activity in progeny of PM mating was 61 . 0 % and 88 . 8 % , respectively .
