STUDY THE TREE FORM FOR Pinus brutia Ten. SPECE IN NINEVAH STANDS

In this study. we were limited the different of tree form for Pinus brutia Ten. In Ninevah stands. By using four methods (form factors. form quotients. form point and stem taper) applications to sample of 56 trees of pinus. We are obtaining the value of absolute F.F.. True F.F. and breast height F.F. (0.34517. 0.4633. and 0.46706) respectively. Also the value of form quotient and form point (0.74596. 0.70676). We are draw graph of stem taper of Pinus brutia Ten. and differential mathematical to estimate the diameter at any level of height tree. The result indicated had significant different between form factors and the other methods. While. there was no significant between the form quotient. form point and stem taper.
