Morphological characteristics of Potentilla fruticosa in the urban ecosystem of Novosibirsk city

摘要

Changes in leaf morphological characteristics in Potentilla fruticosa growing under the transport and industrial pollution conditions in the city of Novosibirsk have been studied. Leaf morphological characteristics were determined by computer image analysis using geographical information systems (GIS). It was found that, in response to anthropogenic disturbance, the size of the assimilating organs of plants decreased by a factor of 1.2-4.5 and the leaf fluctuating asymmetry increased compared to these parameters in control plants; the urban area had a high level of environmental pollution, and the control area a low level.
