The use of plants as monitors of air pollution has long been established as plants are the initial acceptors of air pollution. In Indian cities, unplanned development of industrial and residential areas has further added to this problem. The Total pollution stress of an area affects the growth of various plants in non-uniform manner. Therefore various plant parameters can be used to measure the effect of pollution. Effect of air pollution on two shrub species viz. Calotropis gigantia and Ipomoea Fistulosa at three sampling sites of Indore city were studied. The parameters examined were fresh and dry weight of leaves, L/B ratio, specific leaf area (L/D ratio), size of stomata and stomatal index of the plants growing in polluted habitats. Dust particulates remain in air for varying length of time and get deposited on various plant parts of the plants; especially on leaf surface and affect vegetation of the areas.
