Abstract

The present investigation focuses on stomatal index and chlorophyll contents of species like Datura innoxia L., Capsicum annum L., Lycopersicon esculentum M., Solanum nigrum L. and their comparative account on taxonomic similarity. There were no relation between stomatal size and growth habitat. Our study revealed that Lycopersicon significantly showing reduced in stomatal size and more in number at the lower epidermis, in addition to size of the stomata and subsidiary cells of these species were closely allied. All the investigated species has shown anomocytic stomata. The anatomical structure of subsidiary cells shows irregular in shape, size, and numbers. Irrespective of leaf surface they have peculiar types of anomocytic stomata, stomatal type, and stomatal index. Quantification study of chlorophyll pigment revealed that there is no significant difference among the four species in terms of quantity and taxonomical variations in these species.
