abstract
Survival of plants in the vicinity of industrial areas is being threatened by particulates. This study was aimed to know the effect of cement industries dust on various parts of Mango tree growing at different distances from the cement industrial belt Sarla Nagar, Maihar, Satna (M.P.). Sampling was done at different distances ranging from 0.5-2.0 kms from the point source. The chlorophyll, carotenoid pigments, pH of leaf wash, pH of leaf extract and leaf size (length) were reduced in dustexposed plant species as compared to control site Uchehra (15 km away from the cement factories). Increased concentration of cement dust pollutants causes invisible injuries like progressive decline in photosynthetic ability and closure of leaf stomata and thus affect the growth and productivity of Mango tree. Besides the deleterious effects of the dust were expressed by the reduction in size of the leaf, damaged leaf margin and change in colour. Overall study shows that Mango trees growing near cement industries were adversely affected physiologically.
