Author(s): K Karthika Devi, MH Muhammad Ilyas
Abstract: Micromorphology of trichomes of selective members of Cucurbitaceae like Lagenaria vulgaris, Benincasa hispida, Cucurbita maxima, Luffa acutangula and Cucumis sativus were studied microscopically using scanning electron microscope. The trichomes among the selected members were differ from unicellular to multicellular, conical to elongated, smooth to ridges, with or without flattened disk at base and cystolithic appendages, thin to thick walled, unbranched, glandular or non-glandular. Stomata are minute apertures bounded by two guard cells. They are found mainly in the epidermis of the leaves, they have actinocytic stomata. Large numbers of stomata present in most of the species. This study helps in identifying taxonomically the difference within the selective members with regards to the stomata and trichomes micromorphology.
