A COMPARISON STUDY OF ESTIMATION METHODS OF FORM FACTOR FOR PINUS BRUTIA TEN. IN NINAVA PLANTATION

Abstract

This study was conducted on the floor coverings deployed in the forest irrigation stands for pine trees Pinus brutia Ten. In province of Nineveh, which are located in northern Iraq. The purpose was to know edge and determine the differentiation of main stem shape of pine trees, form study the stem form and taper, by using four methods for this purpose, such as, form factor (ordinary) (Ff), form quotation (Fq), form point (Fp), taper (Ft), for this study, we selected (31) trees randomly. The range of diameter at breast height (6.8–24.8) cm, the study appear differentiation among values of form factor (0.606, 0.403, 0.307) respecting and taper (0.485), therefore, the form quotation (Fq) and taper is proximate same.
