Description
Summary:This paper discusses the physical, mechanical and anatomical characteristics of one-to three-year-old Bambusa blumeana. The physical and mechanical properties such as moisture content, shrinkage, shear and static bending were correlated to the anatomical characteristics. Density and shrinkage, but not moisture content, were significantly correlated to radial/tangential ratio of vascular bundles. Except for the modulus of rupture, all the mechanical properties increased with age, height, density, frequency of vascular bundles and fibre wall thickness. Sifat-sifat fizikal, mekanikal dan anatomikal Bambusa blumeana pada peringkat-peringkat umur satu hingga tiga tahun adalah diperbincangkan dalam kertas kerja ini. Sifat-sifat fizikal dan mekanikal seperti kandungan kelembapan, kecutan dan lenturan statik juga di hubungkaitkan dengan ciri-ciri anatomikal yang di kaji. Melainkan kandungan kelembapan, nilai kepadatan dan pengecutan di dapati berhubung secara nyata terhadap nisbahjejari/tangen berkas-berkas vascular. Kecuali modulus pecah, semua sifat-sifat mekanikal dicerap sebagai meningkat mengikut umur, ketinggian batang, kepadatan, peningkatan taburan berkas-berkas vaskular dan ketebalan dinding gentian.
