Abstract:

【Objective】 To clarify the population composition, geographical distribution, and natural reserve of the composite population resources of wild Awei mushroom in Xinjiang in the hope of providing theoretical support for the conservation, development, and utilization of wild Awei Mushroom resources. 【Methods】 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 isolated strains were identified by molecular biotechnology. Combined with statistical analysis, the population composition, distribution area, and quantitative change trend of wild resources in Xinjiang were clarified. 【Results】 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 identified, 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 Qinghe, 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. eryngii var. ferulae. P. tuoliensis is the dominant population. The overall natural reserves of wild Pleurotus tuoliensis and P. eryngii var. ferulae are showing a downward trend.

摘要：

【目的】研究新疆野生阿魏菇复合群的种群组成、地理分布和自然保有量等,为野生阿魏菇资源保育和开发利用提供理论支撑。【方法】采用普查和样方调查相结合方法,采集新疆野生阿魏菇复合群资源,利用分子生物技术对收集菌株进行种类鉴定,运用统计学分析,阐明新疆野生阿魏菇复合群资源的种群组成、地理分布和自然保有量等。【结果】新疆野生阿魏菇复合群资源由白灵侧耳和阿魏侧耳两个种群组成,白灵侧耳为优势种群,占鉴定总数97.23%,阿魏侧耳为弱势种群,占鉴定总数的2.77%;野生白灵侧耳种群广泛分布在新疆石河子市、托里县、裕民县、额敏县、福海县、富蕴县和青河县等7个区域,而野生阿魏侧耳种群仅分布在托里县、裕民县和额敏县等3个区域;野生白灵侧耳资源自然保有量总体呈下降趋势,且各分布区差异明显,其中石河子市、托里县和额敏县下降幅度最大,样方内年度采集数量最低年份只有0~1株,保育形势严峻;野生阿魏侧耳资源自然保有量极少,5年内在3个分布区样方内仅采集到3株野生菌株,保育形势尤为严峻。【结论】新疆野生阿魏菇复合群由白灵侧耳和阿魏侧耳2个种群组成,白灵侧耳为优势种群,且为广布种;野生白灵侧耳和阿魏侧耳资源自然保有量总体均呈下降趋势。
