Structure of Pit Border in <i>Pinus Strobus</i> L.
AbstractSections fro111 white pine trccs were studied by electrori lllicroscopy in a search for the organization of cell wall layers in the pit border. Depending on the developmental stage of the trachcids, or perhaps on technical imperfections, differences appeared in the pit border within the same tree species. From an electron micrograph of a mature latewood tracheicl, a diagram was reconstructed that appears to be the most representative structure for the pit border in white pine.
