Comparison in the physicaland strength properties of 3 year-old Gigantochloa brang and G.Scortechinii

Relationships between physical and strength properties of Gigantochloa brang and G. scortechinii were investigated. The culms of the three-year-old bamboos were selected, harvested and processed for the studies. The moisture content (MC) of the bamboo in green condition ranged between 74.54 (G. bran...
