Abstract: Discoloration of leaves during autumn is the result of changes in the metabolism of trees and shrubs of temperate climate before winter. Leaves of Parthenocissus inserta growing in different habitats in Cracow were investigated in five terms from July to October. Selected physiological changes: anthocyanin content, chlorophyll content, the state of the cytoplasmic membrane were analyzed in every term of investigation. All of the analysis had two combinations depending on the leaf position in the crown. In the conditions similar to natural coloration of leaves were faster than along the busy thoroughfare where anthocyanin synthesis proceeded very slowly. Directly sunlit leaves were characterized by lower content of assimilation pigments as compared to the shaded leaves.

Keywords: senescence, chlorophyll breakdown, anthocyanins, electrolyte leakage
