Darade M. S.*

ABSTRACT

The effect of dust on leaf injury was observed in fifteen plant species of different families of angiosperms. The leaf area injured in terms of necrosis was studied and percent leaf injury was recorded on different plants of GVISH.institute campus. Out of fifteen plants maximum percent leaf injury was shown by Pongamia pinnata and Ficus religiosa, while minimum percent leaf injury shown by Nyctanthus arbor tristis and Ficus benghalensis.The necrosis of the leaves caused due to dust and its effect on formation of carbohydrate content in leaves was determined. The minimum carbohydrate content was found in leaves of Polyalthia longifolia and Bougainvillea spectabilis, While maximum carbohydrate content is recorded in Nyctanthus arbor tristis, Ficus benghalensis and Annona squamosa. The chlorophyll pigment gets damaged due to deposition of dust and living tissues gets damaged showing necrosis, it affected the formation of carbohydrate content because of less activity of photosynthesis in leaves that affected carbohydrate content.
