Abstract

The study is aimed to examine structural characteristics of leaf for identification of selected Solanum species (Solanum spp.) in terms of trichome number. Eight species in the Genus Solanum, which include Solanum aculeatissimum Jacq., S. indicum L., S. melongena L., S. melongena L. var. esculentum, S. stramonifolium Jacq., S. torvum Sw., S. trilobatum L., and S. xanthocarpum Schrad. & H. Wendl. were selected. Fresh and mature leaves collected from various locations across Thailand and number of dorsal and ventral trichomes in one millimeter squared area were examined under a photomicroscope. Six out of eight species had stellate trichome, while S. stramonifolium had both stellate and multicellular, uniseriate trichome and S. trilobatum had no trichome. Mean, minimum, maximum, and standard deviations were calculated and analyzed. For each species, the average ventral trichome number was higher than average dorsal trichome number. In addition, results showed a comparative data of trichome number among selected Solanum spp.
