Abstract
Correlations between the structure and development of conducting and absorbing roots and ectomycorrhizas of seedlings of Picea obovata and Abies sibirica and their height growth were studied at 1-2, 4.5-7, and 30 km from a copper smelting plant in Russia. The number of mycorrhizas per seedling and the intensity of mycorrhizal development were closely correlated with the development of the aerial part of the seedlings. Such morphological parameters as the length of conducting roots and number of absorbing roots were less important for the development of the aerial parts of the plants.
