Abstract
The anatomical characters of earlywood and
latewood in three mature trees of Blue Pine
were studied. Some of the features observed , do not appear to have been reported in the literature. These are :- the occurrence of crassulae or bars of Sanio on radio walls of earlywood tracheids; Pits with serrate tori on radial walls of early wood and latewood tracheids; Biseriate arrangement of pits on the radial walls of earlywood; occasional occurrence of vestured pits in earlywood ; and occasional occurrence of fused fusiform rays in both in earlywood and latewood.
