Mycorrhiza formation in ash-leaved maple (Acer negundo L.) within the urbanization gradient

Resumo

The development of Acer negundo L. mycorrhiza is analyzed on five sample plots in Yekaterinburg. The plots are organized in an urbanization gradient: from a forest park on natural soils to avenue plantings on sealed soils. It is found that A. negundo L. forms a typical arbuscular mycorrhiza in all habitats. However, as urbanization grows, the quantitative characteristics of mycorrhiza development decrease.
