Keywords: Phleum prаtense L., morphological characteristics, soil industrial pollution, heavy metals.
Effect of heavy metal (zinc and lead) industrial pollution of soil on the morphological characteristics of timothy (Phleum prаtense L.) was investigated. Absolute values of growth parameters were found to decrease near (0.5 km) industrial enterprises compared with relatively “clean” areas. At the same time, the level of within-population variation of most morphological characteristics increased under these conditions. This fact may be an adaptation directed at survival of the population under unfavorable soil conditions. At a distance of 10 km from the source of pollution plants demonstrated only a decrease in leaf dimensions, wherefore this parameter can be used as a diagnostic factor in assessment of the state of populations of the given species growing in areas with heavy metal pollution.
