The grafts were done in March, 2003; and the graft success rate was evaluated at the end of the growing season. 65 % of sucess rate for cleft graft, and 36.7 % of success for veneer graft were designated, at the end of the growing season. The highest success rate was obtained for the cleft grafts which applied on the 3+0 aged stocks with the the scions of the 65 aged ortet tree.trPinus nigra subsp. pallasiana var. pyramidata, Ası, Altlık yası, Ortet, Graft, Stock age,Article
