STUDIES ON STOMATAL RESPONSES OF JAMUN (SYZYGIUM CUMINII) TO EXHAUST PIPE EMISSIONS FROM VEHICLES USING DIFFERENT TYPES OF FUELS

Abstract

Plants of Jamun (Syzygium cuminii) were given exposure to exhaust pipe emissions from vehicles using various fuel types in open top chambers for set duration of time. Stomatal responses were studied in the treated populations. Reduction was noticed in Stomatal size and stomatal frequency in all treated populations of Jamun plants. Maximum reduction in size and frequency was observed in plants exposed to emission from diesel using vehicle. Exposure to harmful pollutants causes changes in normal stomatal physiology and responses in plant species.
