LEAF EPIDERMIS STRUCTURE IN AMELANCHIER OVALIS MEDIC. (ROSACEAE)

The leaf epidermis structure of Amelanchier ovalis Medic. was studied by light and scanning electron microscopy. Rodlets of crystalloid epicuticular waxes and papillae were observed. Simple single trichomes and cyclocytic stomatal type were described. An attempt was made to estimate all features of taxonomic value which are relevant for further clarification of the relationships within subfamily Maloideae. The epidermal structure shows adaptation to various environmental conditions which explains the broad geographical distribution of the specie.
