【中文摘要】 本研究以11個菌株為材料,對原生質(zhì)體無性再生株的單、雙核比例、產(chǎn)菇優(yōu)勢及出菇性狀進(jìn)行了研究。結(jié)果表明:（1）側(cè)耳、香菇無性再生株以“鎖狀聯(lián)合”的有無可區(qū)分為無鎖狀聯(lián)合的單核株和有鎖狀聯(lián)合的雙核株,但其比例因菌株不同而迥異;（2）同一菌株的單、雙核株的菌絲生長速度、出菇期及菇產(chǎn)量等性狀有較大差異,雙核株多優(yōu)于單核株;但原生質(zhì)體雙核株與其親株雙核株相比,優(yōu)劣因菌株而異;（3）無性單核株是進(jìn)行細(xì)胞融合或常規(guī)雜交育種的理想材料,而原生質(zhì)體雙核株可用于選出優(yōu)質(zhì)高產(chǎn)菌株。

【英文摘要】 This study dealt with the ratio between the uninuclear and binuclear strains regenerated from the protoplasts of 11 strains of edible fungi, the yield superiority and their fruiting characters. The results showed that the regenerated strains from the protoplasts of the strains of Pleurotus and Lentinula edodes could be distinguished into the uninuclear strains without "clamp connection" and the binuclear strains with "clamp connection", but the ratio between the above strains was different, that, generated from the same parent strain, the uninuclear strain was markedly different from the binuclear strain in the growth rate of mycelia, fruiting period and yield etc, the binuclear strain was mostly superior to the uninuclear strain, but whether the binuclear strain was superior to the parental binuclear strain depended on the parent strain, and that the asexual uninuclear strain was ideal material for practicing cell fusion or routine breeding, but the protoplasmatic binuclear strain cou...更多l(xiāng)d be used for breeding high-quality and high-yield strains.  還原
