Vynogradova O. Physiologic and biochemical reactions of plants under anthropogenically polluted environment of Donbass

Dissertation is devoted to analysis of the laws of physiological and biochemical reactions of plants to the influence of different quality of technogenic pollution. A decrease of effectiveness of the antioxidative protection under the high level of technogenous load in the assimilation organs of plants is revealed at the Acer platanoides L., Populus dеltoides Marsh. and Pinus sylvestris L., which promotes the activation of lipid peroxidacion, reduction of photosynthetic pigments and rearrangement of the structure of physiologic and biochemical parameters, but the most physiologically caused correlations remain stable. It is revealed, that species specific and change under the influence of the ratio of emission of free and ion-combined fractions of peroxidase in cells of leaves of woody plants. It is first determined, that peroxidase from the leaves of P. deltoidеs growing on the territory of industrial enterprises is more resistant to the direct influence of organic ingredients of emission (phenol and pyridine) compared with the enzyme of control plants. The increased resistance of peroxidase to the effect of phenol and pyridine from the leaves of the seeds progeny of Bromopsis inermis (Leyss.) Holub рopulations, adapted to industrial sites conditions, which are contained in the emission of these plants, is revealed.
