Abstract: Pollen morphology has great significance in field of plant sciences especially in field of Taxonomy and helps to classify and understand the evolutionary history of plants. At present, it plays a key role in taxonomy for identification of plant flora and in forensic department. It contains all genetic information for complete plant. Our observation indicates that non-acetolysed pollen grains of Vigna radiata show reduction in size as compared to acetolysed pollen grains. In case, the effects of healthy and infected plant parts on the nutrient uptake and distribution, it revealed that total N and P and its distribution in selected plant parts such as in stem, leaf, anther and pollen grains clearly declined in infected plant as compare to healthy (control) plant parts due to fungal infection. Present study also indicates that the development of chlorophyll-a and chlorophyll-b are affected by fungal infection in infected plant leaf disc as compare than healthy plant leaf disc. Thus, a comparison of chl-a and chl –b development indicates that in general chl-a development is more as compare than chl-b in both healthy and infected leaf disc of Vigna radiata.
