Abstract: | Present study evaluated the effect of solid waste burning pollution on carbohydrate, stomata and chlorophyll contents of seven different plant species. Leaf samples of Artemisia maritima L., Fraxinus excelsior L., Amaranthus viridis L., Cynodon dactylon L., Chenopodium album L., Robinia pseudoacacia L., and Sophora mollis (Royle) Baker, growing in the (1m, 500m and 1000m distance) vicinity of burning points at residential colony, University of Baluchistan Quetta were collected. Results revealed that the carbohydrate, chlorophyll ‘a and b’ and total chlorophyll contents in the leaves of selected plant species were found to be significantly low at 1m distance, but as the distance from the source of pollution increased (500m & 1000m) these contents increased accordingly. Generally the percentage of completely and partially clogged stomata was found higher near the pollution source (1m distance). The percentage of open stomata in all investigated plant species was noticed lower near the pollution source (1m distance), while with the increase of distance (500m-1000m) the percentage of open stomata increased accordingly. As regard to carbohydrate and chlorophyll contents, the Artemisia maritima L., were found most sensitive to air pollution in all four directions at 1m distances as compared to the other species. While plant species, Cynodon dactylon L. showed more resistant to air pollution effect as regard to carbohydrate contents and high percentage of open stomata at 1m distances with respect to other species. |
