摘要: 通过5年连续调查研究,发现辽宁丹东地区天然次生柞林中及部分柞树经济林中柞树菌根菌种类共有36种,隶属于7个科13个属.在此基础上研究分析了柞树菌根菌的生态分布与共生树种、树龄及季节的关系.结果表明,与蒙古栎共生的菌根菌种类最多,达29种;红菇属种类与柞树共生的树龄范围最广,鹅膏属种类偏重于与树龄较大的柞树共生;夏季的7、8月份为菌根菌发生的高峰期,75%的种类在7月份发生,100%的种类在8月份发生.8月中下旬菌根菌发生的相对密度最高,分别为19.5%和18.4%.

Abstract: With plot cruising and rout investigation methods, 36 species of ectomycorrhizal fungi associated with oaks were found in natural secondary oak forest in Dandong district of Liaoning Province. They were subordinated to 7 familyies, 13 genera. Studies on the relationship of the ecological distribution of mycorrhizal fungi with tree species, tree age and seasons showed that 29 species mycorrhizal fugi preferred to grow with Q. mongolica.The species of Russulla were associated with a wider tree ages of oak, and the species of Amanita were most likely to grow with old tree. July and August were the occurrence peak of mycorrhizal fungi. 75% species occurred in July, and 100% species occurred in August. The relative density of the occurrence number was the highest in mid August (19.5%) and last August (18.4%).
