摘要: 本研究在吉林省西部7个地区13个群落中，调查了杨树菌根真菌的种类和分布，共鉴定出菌根真菌3属8种，其中最多的是球囊霉属，占总种数的75%，在所有调查样点中，菌根真菌物种丰富度最大值为5，球囊霉属物种出现的频度最高为76.92%，各样点菌根真菌对杨树根系的侵染频率平均值为49.44%，侵染强度平均值为37.59%，孢子密度平均值为22.08，各样点菌根真菌侵染频率、侵染强度与孢子密度三者之间均呈极显著正相关，相关系数最大值为0.863。结果表明在吉林省西部杨树群落中存在较丰富的菌根真菌资源，为进一步利用杨树改良盐碱地提供理论依据。
Abstract: The species and distribution of mycorrhizal fungi were investigated in 13 natural communities in 7 regions of western Jilin province. 8 mycorrhizal fungi species were found which belong to 3 genera. There were the most abundant species of Glomus, 75% of all species. The maximum species richness of mycorrhizal fungi was 5, and the highest frequency of species of Glomus was 76.92%. The average infection frequency, infection intensity and spore density of mycorrhizal fungi on poplar roots was 49.44%, 37.59% and 22.08, respectively. There were significant positive correlations among infection frequency, intensity and spore density; the maximum correlation coefficient was 0.863. The results showed that there were abundant mycorrhizal fungi resources in poplar communities in Jilin province, which provided a theoretical basis for further utilization of poplar to improve saline-alkali land.
