Title

MORPHOLOGICAL CHARACTERISTICS AND CHEMICAL COMPOSITION OF GRAPEVINE BRANCHES (VITIS VINIFERA SPP.) GROWN IN ASTARA

Pages

  525-537

Abstract

 This study has been conducted to determine the fiber dimension and chemical composition of GRAPE TREE BRANCHES cultivated in ASTARA, Guilan. For this purpose 53 branches, with identical size and diameter were cut from some grape tree and were sent to laboratory of wood and paper industries in Islamic Azad university ASTARA branch. Inorder to study the MORPHOLOGICAL CHARACTERISTICS of the fibers, samples from the branches were selected at 3 the heights of 5%, 50% and 75%. Fiber separation was done using the method developed by Franklin (1954) and then dimensions of fibers and their biometric coefficients were determined. Wood flour was prepared from the branches with bark and without skin and then, the percentage of CHEMICAL COMPONENTS was determined according to TAPPI standard test methods. The overall average percentage of holocellulose, alpha cellulose, hemicelluloses, cellulose, lignin, extractives soluble in acetone, alcohol, hot water, and cold water and ash were measured as 87.59, 56.99, 30.59, 47.20, 25.16, 5.90, 2.53, 4.41, 1.79 and 1.79 percent, respectively. Also, the average of fiber length, fiber diameter, lumen diameter and cell wall thickness were measured as 0.96 mm, 26.45 mm, 15.48 mm and 5.49 mm, respectively. The averages of slenderness, flexibility and runkel coefficients were calculated as 36.29, 58.50 and 0.71, respectively. The results showed that, the debarked branches of grape trees, the amounts of holocellulose, alpha cellulose, hemi cellulose and cellulose are more than the branches with bark and debarked branches contains less lignin, extractives and ash compared with branches with bark. Also the results showed that dimensions of the fibers including fiber length, fiber diameter and fiber lumen diameter, except cell wall thickness, decreased with increasing of height.
