The use of X-ray method to study annual growth variation of Pinus eldarica

Abstract

Using non-destructive methods to study forest productivity and wood quality as well as annual growth variations deserve special importance. In this regard annual growth changes of Pinus eldarica include width of the spring and summer rings and percentage of tissue structure was determined using X-ray method. Spring wood accounts as the effective factor for growth ring width in pine wood. The annual rings of the tree are thicker in the spring than in the summer time. Pine tree growth rate decreases with age and as the tree age rises, width of the ring as well as spring and summer wood width is lowered.
