以侧耳属菌株为试材,研究了甘肃甘南高海拔地区5个不同侧耳属菌株同一菌种的保藏菌种和子实体组织分离新培养菌种间的生产性能差异情况。结果表明:2类菌种在试管中培养时生长速率没有差异;2类菌种的对峙培养均未产生拮抗现象;组织分离新培养菌种的子实体形态与产量较保藏菌种略显上乘。 The species of Pleurotus ostreatus was used to study the differences in the production performance of the deposited strains and fruiting bodies isolated from the same strain of five different Pleurotus species in the high altitude area of ​​Gannan in Gansu Province. The results showed that there was no difference in the growth rate between the two strains when cultured in vitro. No antagonism was observed in the confrontation cultures of the two strains. The fruiting body morphology and yield of the newly isolated strains were slightly superior to those of the deposited strains.
