食用菌菌种结实性和产量性状早期鉴定的初步研究

实验以34个草菇（Volvariella volvacea）和95个香菇（Lentinula edodes）培养物~(**)为材料,进行了食用苗苗种结实性早期鉴定的研究;以16个侧耳（Pleurotus）~***和14个金针菇（Fla-mmulina velutines）菌株为材料,进行了食用菌菌种产量性状早期鉴定的研究.研究表明,草菇和香菇菌种培养物在平板上的菌落形态特征与结实性有密切关系.草菇培养物的苗落形态还与菌丝形态、长速、酯酶同工酸酶谱、可溶性蛋白带、发菌和出菇等密切相关.侧耳和金计菇菌丝的胸外羧甲基纤维素酶（CMC酶）活力与子实体产量成正相关,可以作为其子实体产量性状早期鉴定的指标之一.

A Primary Study on Early Identification of Fruiting and Yield Characters of Edible Fungus Strain

The fruiting rate of thirty four Volvariella volvacea cultures and ninety five Lentinula edodes cultures and the yield performance of sixteen Pleurotus cultures and fourteen Flammulina velutipes cultures were studied in this paper. Results showed that the stock colony morphology of V. volvacea and L. edodes on plate was closely related to fruiting characters. The colony morphology of V. volvacea cultures was closely related to the hyphal morphology, the hyphal growth rate, the esterase isozyme zymogram, the electrophoretogram of soluble protein, the spawn running and fruiting on the natural substrate. While extracellular CMCase activities of Pleurotus and F. velutipes mycelia at various growth stages, which could be used as one of the early identification markers of fruitbody production characters, seemed to be positively related to the yield.
