The physical attributes, physical and chemcial properties of Gigantochloa scortechinii harvested from FRIM bamboo plantation were studied. For the physical attributes, regardless of age, the culm basal diameter varied from 7.4 to 11.7 cm, culm wall thickness from 1.1 to 3.2 cm, culm weight from 11.2 to 26.4 kg and volume from 11 841 to 21 790 cubic cm. Effects of age on the culm basal diameter, weight and volume were found to be significant except for culm wall thickness. The culm basal diameter, weight and volume correlated positively with age. The top portion of 3-y-old culm showed the highest oven-dry density (0.8 g per cubic cm) while the basal portion of 1-y-old culm the lowest (0.5 g per cubic cm). Highest initial moisture content (131.4 percent) was observed in the basal portion of 1-y-old culm while the lowest at the top portion of 3-y-old culm (58.0 percent). The oven-dry density and initial moisture content were affected by age and culm portion. The initial moisture content was negatively correlated with age and culm portion while the oven-dry density was positively correlated. All the chemical properties varied significanly with age (except for holocellulose) and culm portion (except for ash and lignin content).
