Abstract
As the short rotation coppices (SRC), Salix spp., poplar and yellow poplar, they demonstrate fast growth and asexual propagation ability. Despite the rapid growth characteristics, for use as tree biomass materials, calorific value has not been extensively studied. In this study, it investigated the calorific values belonging to Salix spp., poplar and yellow poplar with particular emphasis on S. gracilistyla., S. gracilistyla and S. caprea showed greater calorific values than those measured with other species(4,546.6 cal g-1 and 4,539.6 cal g-1 respectively). Calorific values were demonstrated to the higher content of xylem tissue. S. gracilistyla from Wonju, YW1-1 and WJ2-9 showed the higher calorific values than other groups and clones. The present results demonstrate higher calorific value and low ash content, and these will be selected asappropriate species and clones for biomass production purpose.
