Abstract:

The comparative analysis of dimensional structure and life strategy of cenopopulations of Chelidonium majus L., Ranunculus acris L. and Taraxacum officinale Webb, ex Wigg. in different functional urban ecotopes is carried out. The specificity of morphometric parameters of the studied plant speciesis is identified, depending on their habitat: the maximum length of Chelidonium majus L. and the smallest length of Taraxacum officinale Webb, ex Wigg.—near the lake and in the park; the smallest number of leaves and flowers—near the plant and in the forest. Fluctuations in length, leaf width and biomass are not observed. T. officinale is sensitive to a recreational load and to the pollutants contained in the emissions of the sugar factory and in the roadside. The perspective of the analyzed parameters as bioindicative signs during biological monitoring and as the markers of ecological status of populations is demonstrated.
