INVESTIGATION ON TREND OF FIBER VARIATION OF PINUS ELDARICA
In this study, annual growth, bark content, fiher dimensions of pine wood (P. eldarica) were measured. Annual ring thickness and bark content 4.95 mm, 12.15% are determined respectively. Fiber length, fiber diameter, lumen cell diameter, cell wall thickness were determined 2.26 mm, 39.63m 29.06 m an...

| Sumario: | In this study, annual growth, bark content, fiher dimensions of pine wood (P. eldarica) were measured. Annual ring thickness and bark content 4.95 mm, 12.15% are determined respectively. Fiber length, fiber diameter, lumen cell diameter, cell wall thickness were determined 2.26 mm, 39.63m 29.06 m and 5.28 m respectively. Also felting coefficient 58.59, tear coefficient 36.24% and flexibility coefficient 18.12%were measured. Trend of variations of fibers dimensions indicated that fibers longth increased with increasing tree height from butt to crown. Also this property increased from pith to tenth annuad ring then decreased toward of bark. Cell wall thickness decreased from butt to 2 m. height and then increased. Also cell wall thickness decreased from pith toward bark. |
