【中文摘要】 在 8個(gè)香菇菌株原生質(zhì)體單核體交配型的測(cè)定中 ,有 4個(gè)菌株測(cè)定出兩種交配型 ,其余 4個(gè)菌株只測(cè)得一種交配型。在得到兩種交配型的菌株中 ,其交配型比例也不是 1:1。進(jìn)一步的實(shí)驗(yàn)表明 ,產(chǎn)生這一現(xiàn)象的主要原因與兩種交配型原生質(zhì)體單核體的再生能力不同有關(guān)。在申香 2號(hào)菌株 10 7個(gè)單核體中 ,AxBx交配型只有 2 6個(gè) ,而且都是在再生階段的前期產(chǎn)生的 ,后期出現(xiàn)的單核體則都是AyBy型菌落。

【英文摘要】 From the result of determining protoplasted monokaryon mating types in 8 Lentinula edodes cultivated strains, it was discovered that two mating types were only found in 4 strains, and only one mating type was found in the rest of other 4 strains, and that in those 4 strains with two mating types, the ratio of two kinds of mating type was not 1∶1. Further experiments suggested that protoplasted monokaryons with different kinds of mating type had different ability of regeneration. In 107 monokaryons of Shenxiang 2 (SX-2), mating type of AxBx was only found in the early regeneration period of 26 protolasted monokaryons, while mating type of AyBy was only found during the later period of protoplasted monokaryon regeneration.
