Green and Dry-Weight Equations for Above-ground Components of Planted Loblolly Pine Trees in the

Prediction equations based on 130 sample trees from thinned and unthinned loblolly pine (Pinus taeda L.) plantations in central Louisiana are pre- sented for the green and dry weights of aboveground tree components. Sample trees ranged from 2 to 21 in. dbh, 18 to 94 ft in height and from 9 to 55 yr in age. Signifi- cant differences in partial stem weight be- tween trees from thinned and unthinned stands required development of separate sets of weight ratio equations. The range of the studies' observations increases the pre- dictive applicability of planted loblolly pine biomass equations.
