Variasi Struktur Anatomi Berdasarkan Tingkat Ketinggian dan Arah Radial dari Kayu Meranti Merah (Shorea parvistipulata)

Abstract

Wide prospects a/utilization will be obtainable when complete data of Shorea parvistipulata and their properties are available. The objective ofthis research was to determine the variation ofthe anaramical properties of S. parvistipulata. Wood sample was taken from cultivated dipterocarp of PT. Balikpapan Forest Industries East Kalimantan. The research used completely randomized design with two factors i.e. axial and radial directions in the stem. Observations ojwood anatomical structures were i" accordance to international Association ofWood Anatomist Standard; included diameter, height and amoullt ofvessel; also height, width and amollnt ofwood rays; percentage oj vessel, percentage oJrays, axial parenchyma andpercentage o/jiber,jiber diameter,jiber lumina, andfiber wall thickness. Result oj the research revealed that wood vessels are solitalY, diffuse porous and consisted ofrare tylosis. Wood rays are multiseriate heterogenous, two types ojaxial parenchyma, i.e.: apotracheal scalariform and paratracheal with narrow long bands. The wood has medium size jibers with thin walled and wide oflumina. Furthermore, the results showed that axial and radial directionJactors in the stem Iwd Significant effect towards anatomicalproperties on S. parvistipulata. There was uniformityforjiber quality, included in category class IJ. It is predicted that woodjiber oj S. parvistipulata can be usedas raw materialjorpaper with smooth sIlt/ace andmedium strength. Key Words: Shorea parvistipulata, anatomical structure, height let-'el, radial direction. ABSTRAK
