Biomass content of black petung bamboo (Dendrocalamus asper (Schult.) Backer ex Heyne cv. Black)

A key issue in the profitability of bamboo plantations is the productivity that can be expected. This study aimed to understand bamboo biomass as well as carbon biomass on Dendrocalamus asber cv. black that was propagated by culm and rhizome cuttings after five years planted. In this study, there were two kinds of black petung bamboo that have been used as samples, namely Dendrocalamus asfier cv. black that was propagated by culm and rhizome cuttings. This study was conducted in bamboo compartment of Bali Botanic Garden. Destructive sampling was used to determine bamboo biomass. Bamboo culms were divided into four parts such as leaves, branches, stems and roots for analysis. The results revealed that averaged bamboo biomass and carbon biomass per hectare for Dendrocalamus asfuer cv. Black propagated by culm and rhizome cuttingswere 38.3 tons and 19.2 tons, and 83.4 tons and 41.7
tons respectively.
