Impact of Crop Tree Release on Wood Properties of Pitch x Loblolly Pine Hybrids

Wood density and growth was determined for loblolly pine (Pinus taeda), pitch pine (P. rigida), and F2 pitch x loblolly pine hybrids which underwent crop tree release by crown touching in 1987. The study site was located in Patrick county in the Piedmont of Virginia. Released trees were compared to trees which remained at the original planting density, 6.6 x 6.6 foot spacing. Pitch x loblolly pine hybrids were compared to pitch pine and loblolly pine to determine species differences. Released trees were free to grow on all sides.
