Abstract: 

Despite the known potential of Kandelia obovata Sheue, Liu & Yong plantation in sequestrating carbon dioxide from the atmosphere, there are relatively few studies including precise estimates of the amount of carbon in these plantations. In this study it was determined the biomass-carbon conversion factors for stems, branches, leaves and roots of Kandelia obovata Sheue, Liu & Yong plantation in the coastal provinces of Northern Vietnam. We developed allometric equations to estimate the total and different tree component amount of carbon and biomass. A total of 101 sample trees were fell, measured and sampled for biomass and carbon analysis at a single tree level. The biomass-carbon conversion factor for stem, branch, leaf and root components and total tree were 49.48%, 48.41%, 51.94%, 49.46% and 49.55%, respectively, which are slightly greater than the values in other studies and smaller than the generic value commonly used (50%). The best-fit allometric equations to estimate the aboveground, belowground and total amount of carbon and biomass were also determined.
