【中文摘要】 平菇(Pleurotus sapidus)、香菇(Lentinus edodes)及其融合子后代子實體的細胞學觀察表明:平菇、香菇的擔子細胞及核分裂行為均屬正常,而融合子后代的擔子細胞發生異常,其擔子細胞頂端出現粗大伸長的擔子梗,其中有的形成一個孢子。處于終變期的染色體收縮成小球狀,其數目多于雙親染色體,分裂后期出現落后染色體,融合子后代子實體不形成孢子印,鏡檢發現有少數孢子。融合子所產生的孢子與雙親的孢子相比較,在形態特征及大小上均有較顯著的差異。

【英文摘要】 The cytological observation of fusants progeny fruitbody from intergeneric protoplast fusion of Pleurotus sapidus and Lentinus edodes showed that basidium cells and nucleus division of Pleurotus sapidus and Lentinus edodes were normal. But the basidium cells of fusant were unnormal. An elongated and thick sterigma on the apex of basidium was observed and some of which formed a spore. The chromosomes in diakinesis phase were contracted as a small sphere. While the number of chromosome in the fusants was more than that of their parents and lagging chromosomes were found during mciotic anaphusc. Spore print could not be formed from fruitbody of fusaut progeny althrough a few spores were found under microscope inspection and spores from fusants were different in size and morphology with those from their parents.
