vSOME MORPHOLOGICAL AND PHYSICAL CHARACTERISTICS OFBOXWOOD (Buxus sempervirens L.)(M.Sc. Thesis)Esra TÜRKYILMAZGAZI UNIVERSITYINSTITUTE OF SCIENCE AND TECHNOLOGYJune 2005ABSTRACTIn this study, some morphological, physical and chemical characteristics ofBoxwood (Buxus sempervirens L.) were determined. The boxwoods used in thisexperiments were selected from Cide and Pınarbaşı State Forest Enterprises.For the anatomical characteristics, leaf thickness, the thicknesses of the upperand lover ephidermis, palisade and spongy parenchyma were determined.Besides, vessel members dimensions, number vessel of per 1 mm2, number ofrays per 1 mm, fiber dimensions, cell wall thickness were measured on woodsamples. Also, specific gravity, cell wall material, air space volume per centage,wood density, shrinkage and swelling properties were determined as a woodphysical characteristics. In addition, extractive contents of wood, bark and leafwere determined. As a result, vessel members length, radial and tangentialvessel diameters, vessel number per 1mm2, number of rays per 1 mm, fiberlenght, fiber width, fiber wall tickness and lumen width, leaf thickness,mesomorphy thickness, oven dry specific gravity, density, ash content, alcoholsolubility were obtained as 452,09 µm, 22,22 µm, 22,27 µm, 127,83 adet, 13,63adet, 665,57 µm, 17,37 µm, 6,60 µm , 4,17 µm, 380,52 µm, 360,07 µm, 0,91 g/cm3,0,79 g/cm3, % 0,85, % 7,5 respectively. Because of high specific gravity boxwoodshould be used as lathe works and production of small ornaments and advisableto the areas where the dimensional stability and the wearing are important.viScience Code : 502.19.00Key Words : Boxwood, Anotomical characters, Specific gravity, Shrinkageand swelling propertiesPage Number : 75Adviser : Prof. Dr. Hasan VURDU
