Abstract

PAULOWNIA (PAULOWNIA fortunei) is one of the exotic tress which has been successfully growing in Gorgan region since twenty five years ago. The eight years old PAULOWNIA trees have born hundred percent juvenile wood, in which FIBER length for the first and eighth annual rings were measured 0.800 and 1.11 mm respectively. POSTCAMBIAL growth of FIBER length begins starting from the sixth annual ring. FIBER diameter and thickness in the first annual ring were 31.00 and 4. 14 and in the eighth annual ring 33.18 and 5.18 micrometers respectively. A maximum coefficient of variation was found for FIBER thickness, while a minimum value obtained for FIBER diameter. Minimum FIBER diameter variation was observed starting from first to eighth annual rings, in which FIBER indices were measured 26 and 34 respectively. Water soluble EXTRACTIVE MATERIAL was measured 6.94%, the most among all solutions.Aceton and aceton+alcohol soluble and extractable materials were 5.05% and 4.88% respectively, very similar to each other. Average LIGNIN content was calculated as 29.77%,that is pretty high and comparable with coniferous, LIGNIN content. CELLULOSE and HEMICELLULOSES contents were measured as 45.55% and 24.66% respectively.
