The Use of the Parameters of Chlorophyll a Fluorescence Induction for Assessment of Plant State under Anthropogenic Load
The te^nique for rerarding of ^^TOphy!! a f1uorescence indud;ion kine^s has been used for assessment of the physiological state of leaves of tillet (Tilia cordata), pendent white birch (Betula pendula), Amerkan arborvitae (Thuja occidentalis) in urban environments. Different sensitivity of plants to adverse growing randitions was observed. The most sensitive JIP test parameters s^h as PIabs, Fv/F0, Fv/Fm, Rfd are determined to be used as radiators of the physiolog^al state of urban phytocenosis. Rerammendations for the appl^ation of this te^nique in monitoring studies are given.
