The aim of this study was to study physical characteristics of bamboo 6 varieties including Sang nuan bamboo (Dendrocalamus membranaceus Munro), Sang mon bamboo (D. sericeus Munro), Poe mae tawo bamboo (D. copelandii1), Man moo bamboo (D. copelandii2) Ruak bamboo (Thyrsostachys siamensis) and Kim sung bamboo (Bambusa beecheyana) at culm aged 1 year, 2 years and 3 years, by cutting the middle of the culm in the same length at 20 cm then weight and measure. Determine the physical characteristics of bamboo are including moisture, shrinkage and density. The results showed that there was no difference in density of each bamboo at culm age 1, 2 and 3 years. However, the D. membranaceus at culm age 1 year yield the highest density at 804.38 kg/m3, and the D. membranaceus had the lowest moisture content and shrinkage at 8.42% and 11.69%, respectively. The studied bamboo varieties at culm age 2 years D. membranaceus had the highest density at 736.66 kg/m3 Meanwhile, B. beecheyana had the lowest moisture content and shrinkage at 8.23% and 10.21%, respectively. The studied bamboo varieties at culm age 3 years T. siamensis had the highest density at 777.59 kg/m3, B. beecheyana had lowest moisture content at 7.73% and D. membranaceus had the lowest shrinkage at 7.51%.
