Özet:

 In this study, the morphological characteristics and distribution of glandular trichomes on the vegetative and generative organs of endemic two Sempervivum taxa Sempervivum brevipilum and Sempervivum gillianiae were comparatively investigated. S. brevipilum is the Irano-Turanian element and S. gillianiae is the Euxine element. In the trichome examinations, cross and surface sections were taken from the stems, rosette leaves, sepals and petals of the taxa. The trichomes were grouped under three groups as capitate, multicellular biseriate and uniseriate glandular trichomes. The multicellular biseriate and uniseriate glandular trichomes were observed on both vegetative and generative organs of the two taxa. In addition, capitate glandular trichomes one or two stalk and head celled were found on the organs of these taxa. Similar and different trichome features were given in tables. Mann Whitney U test was applied to the measurement results of trichomes features. No significant differences were found in the density and sparseness of long and short multicellular biseriate and uniseriate, capitate glandular trichomes. However, differences in the lengths of multicellular biseriate, uniseriate glandular and capitate glandular trichomes on the vegetative and generative organs of these two taxa were seen p0.05. It was emphasized that different trichome characteristics especially trichome length are valuable taxonomic characteristics that can be used to distinguish these two Sempervivum taxa.
