Betechtina A.A., Veselkin D.V. ACCORDING TO THE RESULTS OF INDIRECT COMPARISONS INVASIVE PLANTS FORM MYCORRHIZA LESS INTENSE THAN ABORIGINAL PLANTSIn this paper the successful interaction of invasive plants with arbuscular fungi was investigated. Most discussed material was obtained in the Middle Urals in Yekaterinburg and surroundings. Invaders Acer negundo L., Heracleum sosnowskyi Manden., Hordeum jubatum L., Impatiens glandulifera Royle and all comparatively regarded aboriginal plants are located here. Two species considered as invaders are located outside the Sverdlovsk region, Cyclachaena xanthiifolia (Nutt.) Fresen. Is located in Samara region (Tolyatti), Ambrosia artemisiifolia L. is located in Krasnodar region (Krasnodar). All studied invasive species with the exception of Impatiens glandulifera showed typical arbuscular mycorrhiza. Found mycorrhiza of alien species corresponds to the published data. Mycorrhizal status of Heracleum sosnowskyi appairently was defined for the first time. The occurrence of fungi in the roots of the five studied mycorrhizal invasive species is lower than in aboriginal plant species. It was determined that these differences are not due to taxonomic or biomorphological features of invasive species.Key words: plant invasion, invasive plants, arbuscular mycorrhiza.
