Differences in the anatomy of root bark and stem bark in some conifers


, : Differences in the anatomy of root bark and stem bark in some conifers. Lesnoi Zhurnal (3): 5-9

A comparative anatomical analysis was made of the bark of roots, stems and young shoots of Abies sibirica, Pinus sibirica, Picea abies and Larix sibirica. Differences were observed between stem bark and root bark as regards histology, tissue topography, tissue development and changes with age.
