研究了５１株Ｐｌｅｕｒｏｔｕｓ菌株的营养菌丝体的形态学、细胞学和生理生化特性．结果表明：菌落形态、无性孢子、细胞结构的变化，菌丝体胞外纤维素酶活力、ＴＴＣ－脱氢酶活力的变化，酯酶（ＥＳＴ）、过氧化物酶（ＰＯＤ）同工酶谱的异同，可作为鉴定菌株变异的主要标记．应用这些标记，确定了Ｐ．ｆｌｏｒｉｄｅ和Ｐ．ｏｓｔｒｅａｔｕｓ的两株变异株
The morphological, cytological and biochemical characteristics of vegetative mycelia of 51 strains of Pleurotus were studied. The results showed that: the morphology of colony, the changes of asexual spores and cell structure, the changes of mycelium extracellular cellulase activity, TTC-dehydrogenase activity, esterase (EST), peroxidase (POD) The similarities and differences can be used as the main marker to identify the variation of strains. Apply these markers to determine P. floride and P. Two variants of ostreatus
