Abstract

Environmental deterioration in India is eminent due to rapid industrialization and intense urbanization due to industrialization. The poor air quality is one of the most serious environmental problem in the world. Transportation, industrial power generation, toxic substances, gases in the atmosphere have effect on our food supply, health, plant human life and economy.

Present study deals with the observation made on the plants on roadside in comparison to plants in controlled area. On roadside plants having heavy auto-exhaust pollution load.

Present studies were made on Cassia occidentalis taken from Garh road, Railway road, Delhi road and University road. These changes have been worked out on the basis of percentage of reduction in various parameters in tested plants.

Due to high concentration of automobile pollution, the number of stomata, stomatal index and stomatal density were reduced and Number of epidermal cells and epidermal density were increased.

Variation in stomatal index and stomatal density on the adaxial and abaxial surface has been observed in these plants.
