【摘要】 取發(fā)生不同程度菌種退化的相同來源的金針菇(Flammulina velutipes)工廠化袋栽菌株和栽培菌包,觀察其在PDA平板上的分純情況和形態(tài)特征;采用LBL液體培養(yǎng)基檢測不同菌株對培養(yǎng)基的脫色情況。實驗結(jié)果表明:這些退化菌株經(jīng)過分離可以得到不同菌落形態(tài)的分離菌株,而且對LBL液體培養(yǎng)基表現(xiàn)不同的脫色能力,退化嚴(yán)重的菌株脫色能力最差,說明LBL液體培養(yǎng)基的脫色反應(yīng)結(jié)合菌種純度的檢測可以在一定程度上排除生產(chǎn)上的退化菌株。
【Abstract】 Three Flammulina velutipes cultivars,designated KW,YH and YQ,originally derived from the same source strain and adopted individually by three different companies for commercial cultivation,exhibited different degrees of degeneration manifested by the delayed formation of primordia(from five to 30 days) or the inability to form fruit bodies.Following subculture from either stock culture slants or cultivation bags on to potato dextrose agar,each source gave rise to several different morphological ...
