PY - 2014/04/01 TI - Morphology of Betula pendula var. carelica bark at the pre-reproductive stage JF - Modern Phytomorphology; Vol 6 (2014)DO - 10.5281/zenodo.160622 KW - N2 - Changes in bark morphology at the pre-reproductive stage of Karelian birch are for the first time considered in connection with the type of trunk surface. The bark surface in Karelian birch changes with age from smooth to fissured. At the pre-reproductive stage Karelian birch has smooth bark with different types of exfoliation of the phellem surface layers, and tubercular specimens feature locally fissured bark on muffs at the very onset of their formation, as well as early rhytidome formation. Morphology of the bark tissues complex is a reflection of direction and intensity of the internal processes of the plant. UR - http://ojs.phytomorphology.org/index.php/MP/article/view/147
