Abstract: | Saplings of Tamarindus indica, Mangifera indica, Pithecolobium dulce, Ficus rumphii, Ficus bengalensis, Holoptelea integrifolia, Syzygium cumind, and Psidium guajava were exposed to varying concentrations of SO2 and chlorophyll, protein, amino acids, starch, total soluble sugars and reducing sugars were determined. In general, it was observed that on exposure to SO2 in susceptible plants most of the biochemical constituents accumulated in higher amounts while in plants showing visible damage at extremely high exposure concentration a reverse pattern was obtained. |
