Abstract
The changes in morphological characteristics of leaf and elemental composition of the above-ground organs of Potentilla fruticosa L. plants growing in the conditions of transport and industrial pollution in Novosibirsk were analyzed. The content of heavy metals - iron, nickel, vanadium and titanium in the above-ground organs of plants of street plantings increased by 1.3-9.5 times compared with the control. In response to the technogenic effect the size of the leaf assimilative organs decreased, and the value of fluctuating asymmetry index of the leaf terminal lobe compared to that of the background P. fruticosa plants increased. According to this index, environmental quality of the urban zone corresponds to the high level of pollution, of the background one to the low level.
