COMPARATIVE MICROMORPHOLOGY AND ANATOMY OF CHRYSOCHAMELA (FENZL) BOISS. (CRUCIFERAE) GROWING IN TURKEY

The micromorphological and anatomical characteristics of three species of Chrysochamela genus have been comparatively presented by using light microscopy (LM) and scanning electron microscopy (SEM). The micromorphological studies are related to the epidermal and seed surface. In anatomical studies, cross sections of the stems and leaves were examined and biometric measurement of cell and tissues were made. The stem and leaf anatomy of the genus were described. In addition, the stomatal index rate and stomatal index of these species were calculated. The leaf is dorsiventral in mesophyll-type. Except its C. noeana taxon, stellate trichomas are coincided in other taxon. Stoma can be observed on both sides of the leaf. Whereas stoma index rates of this genus were found in the range of 0.7 - 1.2, stoma types were observed as aniocytic and anomocytic. Seed surface of the genus can be found in reticulate, verrucae or in verrucaerugose types. In conclusion, the presence/absence of trichome over stem and leaves, the presence/absence of collenchyma in middle the vascular region, the seed shape, epidermal cell shape, and the characteristics of anticlinal boundaries and periclinal cell walls were found to be the important characters for identification of the Chrysochamela genus.
