A Morphometric Study of Epidermal Appendages in Commonly Existed Angiosperms in Faisalabad, Pakistan

Epidermal appendages are mono-cellular or multicellular, root hairs, and trichomes that grow on an epidermis. Commonly found members of angiospermic families were selected focusing on their presence or absence, position, and types of surface appendages (colliculate, hairy, wart and papil). Trichomes types (simple hairs, tubercle-based hair minerals) concrete, secretory hairs, vesicular hairs, moniliform hairs, and dendritic hairs were also considered. The epidermal appendages were studied in thirty species of angiospermic families collected from Botanical Garden University of Agriculture Faisalabad, Pakistan, by using light microscope. The data was then subjected to ANOVA and cluster analysis to investigate relationship among different angiosperm species. The Maximum cell length/width on abaxial epidermis is recorded in Strelitzia reginae Regel & Koch and Terminalia bellirica (Gaertn.) Roxb, which is closely related to the Alpinia allughas Retz., and Crinum asiaticum L.. Minimum cell length on upper epidermis is recorded in Ficus lyrata which is closely related to the Colocasia esculentum. Maximum number of stomata is observed in Kigela africana. Minimum number of stomata is recorded in Terminalia bellirica and Ficus lyrata. Maximum number of stomata on adaxial epidermis is recorded in Pentas lanceolata. Minimum number of stomata is recorded in Ravenala medaghas cariensis. On adaxial surface, the maximum number of trichomes is recorded in Terminallia bellirica and Kigela Africana, and the minimum number is recorded in Campsis rodicum. The present study emphasizes the distinctive and similar features of those epidermal appendages. These o
