Effect street light pollution on the photosynthetic efficiency of different plants

The present study was conducted to study the effect of light pollution on the photosynthetic efficiency of plants growing near to street light. The photosynthetic parameters Fv/Fm (Fm - Fo/Fm); maximum photochemical quantum yield of PS II (photosystem II), Y II (photochemical quantum yield of photosystem II), Y (NPQ), Y (NO) were recorded with the help of JUNIOR-PAM, Chlorophyll Fluorometer, Heinz Walz GmbH, Germany. It was observed that various parameters were adversely affected and the observed values show that plants is under some sort of stress which may be disturbing their normal physiological processes.
