The use of parameters of chlorophyll a fluorescence induction to evaluate the state of plants under anthropogenic load

The physiological state of the leaves of the small-leaved linden (Tilia cordata), silver birch (Betula pendula), and northern white cedar (Thuja occidentalis) under urban conditions was assessed via recording the kinetics of chlorophyll under fluorescence induction. Different sensitivities of the plants to adverse growing conditions were revealed. The most sensitive parameters of the fluorescence JIP test, viz., PIABS, FV/F0, and FV/FM, were identified as indicators of the physiological state of the urban phytocoenosis. Recommendations for the application of the method for monitoring studies are presented. © 2015, Pleiades Publishing, Inc.
