There are researches of many years of biological characteristics (fertility, vegetative propagation and other) in introduced species of Cornaceae family in the Ukraine, while there are few data on leaf micromorphology of these plants. The aim of our work was to investigate the anatomy and morphology of leaves of Cornaceae species. Cross sections of leaves were prepared and staining using standard histological methods, light microscopy and scanning electron microscopy were made. It was shown that all investigated species have the similar leaf anatomy: single- layer upper and lower epidermis covered with a cuticle and trichomes, the stomata are on the lower leaf side, the mesophyll consists of the palisade and spongy parenchyma. In the same time, there are differences in the anatomical quantitative features: size and number of stomata, number of trichomes, size of cells, leaf blade thickness, and the palisade ratio. We can claim about successfully adaptation of the investigated species based on their anatomy without any destructive features and every year flowering and fruiting (according to the previous data). This work may serve as a basis for further investigations of introduced species of Cornus and monitoring of their condition under introduction. [ABSTRACT FROM AUTHOR] |
