Anatomical study of PrunusL species wood in Iraq

The genus Primus L. belongs to the Rosaceae family; there are therteen species of prunus which are grown wildly and cultivated in Iraq namly: (P. cerasijea , P. xdomestica , P. armeniaca , P. persica , P. amygdctlus , P. Arabica , P. orientalis , P. kotschyi , P. cardiichomm , P. microcarpa , P. brachypetala , P. mahaleb, P. cerasus], This study was designed to investigate some of the anatomical features of wood. The species under investigation showed that the secondary wood of all species studied is sem-ring porous wood and the porous aqre not uniformly distributed through out the annual growth ring. The pores are mostly solitary or arranged in a radical chains consisted of (2-5) pores. The vessels thay have a simple perforation plate with spiral and Scalifonn thickness; the cells of axial parenchyma are apotracheal diffuse type. Generally, the main dimension of vessels. Tracheids, rays and fibers in P. xdomestica and P. cerasus was shown tobe higher than in others species.
