Апстракт:
Mycorrhiza is an association of primary significance for the functioning of forest ecosystems, important for assessing forest resilience to current climate change and pollution. Our aim was to compare diversity of ectomycorrhizal fungi on poplars from differently polluted sites and to determine reliability of diversity parameters for bio-indication. Three sites were compared: i) a natural, unpolluted site of native poplars (KR) ii) a site with ozone concentration in the air above the critical ozone level for forests (A), iii) a site which was contaminated with heavy metals and had low pH (T). Number of ectomycorrhizal types on investigated sites was 15, 6 and 4, respectively. Average values of number of ectomycorrhizal types, vital root tips, old, nonturgescent and nonmycorrhizal roots and diversity indices per soil sample were compared. In samples from sites KR, A and T the Species richness index was 1.63, 0.78 and 0.14 and Shannon-Weaver index 1.15, 0.63 and 0.14, respectively. The highest values of ectomycorrhizal types’ number and diversity indices were recorded at the unpolluted site, while the lowest values were observed at the most extreme site. So, diversity of ectomycorrhizal fungi could be considered as a reliable indicator of forest ecosystem’s resilience in poplar sites.
