The effects of one-step and two-step pruning treatments on tree taper of loblolly pine (Pinus taeda L.) were compared in this study. Girard form class and a segmented taper equation were used as two measures of stem form. There was a significant difference in stem form between trees subjected to one-step and two-step pruning treatments at the 5% probability level. Trees pruned at ages 6 and 11 tapered less and yielded about 4% more cubic-foot volume and 9% more board-foot volume than trees pruned at age 11 of comparable diameters and heights. South. J. Appl. For. 10:251-253, Nov. 1986.
