Stem Sinuosity of Loblolly Pine Seedlings as Influenced by Taproot Shape

Murphy, M. S. and Harrington, T. B. IN: Proceedings of the 12th biennial southern silvicultural research conference, p. 465-468. USDA Forest Service, Southern Research Station, General Technical Report SRS-71. Kristina F. Connor, ed. 2004.

Abstract—Sinuous stem growth in loblolly pine (Pinus taeda L.) results in diminished potential for the utilization of wood products since these stems are difficult to mill and contain a higher percentage of compression wood. In this study, 90 full-sibling loblolly pine seedlings (30 seedlings from each of 3 families) were planted with 5 taproot configurations: straighttaproot (check treatment), straight taproot with underground obstruction, taproot planted with “J” shape, straight taproot planted at a 45 degree angle, and a straight taproot with the stem guywired to a 45 degree angle.
