CHARACTERIZATION OF ANATOMICAL, MORPHOLOGICAL, PHYSICAL AND CHEMICAL PROPERTIES OF KONAR (ZIZIPHUS SPINA-CHRISTI) WOOD

The goal of this research is to investigate some morphological (fibre length, fibre diameter, cell wall thickness, Runkel coefficient, flexibility slenderness rigidity Luce's solid coefficient), physical (dry wood density, volumetric shrinkage) and chemical (cellulose, hemicellulose, lignin, ash acetone soluble extractives contents) composition Konar (Ziziphus spina-christi) grown in Hormozgan province, Iran. For purpose, three normal trees were selected randomly a disk was cut from each one at breast height. Anatomical inspection revealed that the species diffuse porous, with distinctive growth rings, simple preformation plate, polygonal openings, banded or diffuse-in aggregates parenchyma. average values dry fiber felting Luce’s coefficient 0.926, 52.1, 77.85, 0.57, 163 ×103 μ3 0.48.
