ABSTRACT CORTEZ JR, FRENEO A., Department of Resource Engineering and Agricultural Mechanization, College of Engineering and Computer Studies, Pampanga State Agricultural University, Magalang, Pampanga. August 2022. "Determination of Ph sical and Mechanical Pro: rties of Different Bamboo S: - ies" Adviser: Dr. Lyndon G. Solis This study aimed to determine the physical properties i.e, length, weight, diameter, number of internodes, length of internode, culm wall thickness, moisture content, density, shrinkage in diameter and culm wall thickness and mechanical properties i.e, compressive and flexural strength) of Bolo (Gigantochloa levis), Bayog (Bambusa spinosa), and Kawayan killing (Bambusa vulgaris) at different height position. A total of nine (9) bamboo culms of at least four (4) years old was used in this study with twenty-seven treatments. Each culm was divided into three portions. Two factorial analysis of variance (ANOVA) was used as the experimental design. According to the study's findings, Gigantochloa levis had the highest recorded value in terms of length, weight, diameter, length of internode, and shrinkage in culm wall thickness. Bambusa spinosa recorded the highest value for culm wall thickness, moisture content, and shrinkage in diameter. Bambusa vulgaris had the highest mean value for number of internodes and density. Additionally, Bambusa vulgaris had the highest compressive and flexural strengths.
