【中文摘要】 對我國現栽柳松菇菌種遺傳特征及生活史的研究發現,該菇由菌絲生長的營養生長階段進入原基分化發育的生殖生長階段,可產生正常的子實體。電鏡觀察可見成熟的擔子上著生雙孢擔孢子,單個擔孢子遇適宜條件萌發形成有鎖狀聯合的菌絲體,并自交可孕,基于柳松菇具有次級同宗結合菌的單孢可育特征,我們采用單孢分離方法進行品種選育,獲得了出菇菇叢密、菇數多、產量高的單孢菌株。

【英文摘要】 The genetic characteristics and life cycle of A. cylindrui fa cultivated in China were studied. Well-developed A. cylindracea fruitbudics were formed on ce tain substrates when it transformed from vegetative phase to generative phase. And two busilioripores on each basidium were observed with electron microscope. The single basidiosporc easily gcnninatcd and the hyphae Rearing clamp connections were self-fertile. It was deduced from our results; that the sexual system of this fungus was similar to the secondary homothallicT species of biisiiliomycctos of which the single basidiosporc culture was self fertile. Therefore, we improved the strains of A. cylindracea by single basidiosporc isolates selection and obtained the prospective si rains with high yield and good quality.
