MICROMORPHOLOGICAL ASPECTS REGARDING THE LEAVES ON SOME ROSES WITH EMPHASIS ON SECRETORY GLANDS

摘要

The multicellular glands, the epicuticular wax and the tector hairs observed on the leaves are influenced usually by genetic constitution.The paper investigating 8 genetically related varieties: ‘Foc de Tabara’, ’Luchian’ ‘Paprika’, ‘Coup De Foudre’, ‘Independence’, ‘M-me A. Meilland’, ‘Cocktail’, ‘Laminuette’.The micromorphological studies evidencing some characters with a certain value for diagnosis. These may be used in investigation concerning to the identification when the flower is absent. Our study underlines micromorphology aspects of glands, epicuticular wax and tector hairs. All of them were been examinating through scanning electron microscopy method.
