新疆野生阿魏菇复合群的种群结构及地理分布OA北大核心CSTPCD

[Objective]To clarify the population composition,geographical distribution,and natural re-serve of the composite population resources of wild Awei mushroom in Xinjiang in the hope of providing theo-retical support for the conservation,development,and utilization of wild Awei Mushroom resources.[Meth-ods]The regional investigation and collection of wild Awei mushroom compound group resources in Xinjiang were carried out by adopting the method of combining general survey and sample survey.The species of isola-ted strains were identified by molecular biotechnology.Combined with statistical analysis,the population com-position,distribution area,and quantitative change trend of wild resources in Xinjiang were clarified.[Re-sults]The wild Awei mushroom composite group resources in Xinjiang are composed of Pleurotus tuoliensis and P.eryngii var.ferulae.P.tuoliensis was the dominant population,accounting for 97.23%of the total identi-fied,and P.eryngii var.ferulae was the weak population,accounting for 2.77%.The distribution areas of the wild P.tuoliensis resources in Xinjiang included Shihezi,Tuoli,Yumin,Emin,Fuhai,Fuyun and Qing-he,and the wild P.eryngii var.ferulae resource in Xinjiang was only distributed in Tuoli,Yumin,and Emin.The natural population of wild P.tuoliensis resources had a downward trend in general,and there were great differences in distribution areas,among them,Tuoli,Shihezi and Emin had the largest decline,and only 1 or 0 plant was collected when the annual collection quantity was the lowest in the sample area.[Conclusion]The wild Awei mushroom composite group resources in Xinjiang are composed of Pleurotus tuoliensis and P.er-yngii var.ferulae.P.tuoliensis is the dominant population.The overall natural reserves of wild Pleurotus tuo-liensis and P.eryngii var.ferulae are showing a downward trend.
