Characterization of ultrastructure of the leaf surface in species of the genus Pilosella Vaill. (Acteraceae) in the Crimean flora

Pavlenko-Barysheva V.S.
Abstract

For the first time the surface ultrastructure of leaf epidermis of 12 species of the genus Pilosella in the flora of Crimea was studied using SEM. Both common (amphystomatic features, arrangement of stomata relative to the level of basal epidermal cells, crystalloid and crusts types of wax deposits; anomocytic type of stomata) and specific characteristics of the leaf ultrastructure of the studied species have been revealed. Most of them are additional diagnostic characters on the sectional level (surface relief type, presence and type of trichomes) and the species level (surface relief type). Similar surface ultrastructure of leaf epidermis in hybrid and parent species was found.

Keywords: Pilosella, Praealtina, Echinina, leaf, SEM, surface ultrastructure of leaves, Crimean flora
