长白山地区蜜环菌属真菌资源

Investigation of Armillaria Fungal Resources in Changbai Mountain Area

蜜环菌属Armillaria真菌是长白山地区代表性野生菌,具有重要的食药用价值。本研究采用样方调查和随机踏查相结合的方法对该地区蜜环菌属物种展开资源调查和种类鉴定,结果表明,长白山地区蜜环菌有5种,即北方蜜环菌Armillaira borealis、法国蜜环菌A.gallica、黄小蜜环菌A.cepistipes、芥黄蜜环菌A.sinapina以及Armillaira sp.,其中北方蜜环菌为吉林省新记录种,法国蜜环菌为该地区的优势物种。多样性分析结果表明,在阔叶林、针阔混交林、针叶林3种林型中,针阔混交林中蜜环菌属α多样性指数相对较高,说明针阔混交林的物种丰富度最高。本研究为蜜环菌属资源的开发和利用提供理论基础和实践依据。

Armillaria is a representative wild fungus in Changbai Mountain area of Jilin,with greatly importance of edible,medicinal,economic,and ecological values.Investigation and species identification of Armillaria were carried out within this area by sample investigation and random inspection.The results showed that there were 5 Aimillaria species in Changbai Mountain,namely A.borealis,A.gallica,A.cepistipes,A.sinapina,and Armillaira sp.,in which A.borealis was the species newly discovered in Jilin Province.A.gallica was the dominant species identified in the Changbai Mountain area.Investigation of distribution patterns of the species with three different types of forests indicated,furthermore,that Armillaria had the highest species-richness within the mixed coniferous forest as compared with that within the broadleaf forest and coniferous forest.The study provides theoretical and practical basis for the future development and utilization of Armillaria resources.
