However, there are large differences in biomass production among clones, and within a clone planted on different edaphic conditions. Therefore, it is important to quantify the biomass production and carbon budget of poplar plantations for a wide range of environmental conditions. In this study, we compare the aboveground biomass allometric equations for two clones of poplar (D105 and NM6) grown on an upland and lowland site in the Arlington,WI. Each site contained replicated plots of each clone. A total of 10 trees (except at the lowland site where 9 trees were sampled for D105) of each clone at each site were destructively sampled for a total of 39 trees. Simple linear regression equations were developed using linear least squares regression analysis to estimate aboveground component biomass (stem, branch, and foliage) and leaf area from diameter at breast height (dbh).
Results/Conclusions
Total of 16 simple linear regression equations are composed for two clones and compared to each other to reveal the clonal and edaphic differences. The allometric equations had R2 values that ranged between 0.63 and 0.98. Biomass and leaf area allometric equations differed significantly between clone type and edaphic condition.
