Variability of Understory Sweetgum Biomass Relationships
Understory sweetgum (Liquidambar styraciflua L.) in three 40-50-yr-old stands of loblolly pine was sampled to estimate the total and component biomass encompassed by this species. Individual tree sweetgum equations (based on D²H) were developed for total tree and tree component biomass for each stand. Total stand estimates of 9.79, 8.38, 1.09, and 0 32 tons/ac were determined for total, stem, branch, and foliage dry weight, respectively. There were no statistical differences among stands for total tree and stem biomass equations, but differences were found among stands for foliage and branch equations. The differences among crown component equations are probably reflective of the understory growing conditions in the different stands. South. J. Appl. For. 12(1):5-7.
