Field Performance of Shortleaf Pine Half-Sib Families Though 10 Years in the Ouachita Mountains of Arkansas

Abstract

Shortleaf pine (Pinus echinata Mill.) seeds collected from six half-sib families were grown as both bareroot and container stock and outplanted on two sites in the Ouachita Mountains of Arkansas. Survival and growth were measured at years 1, 3, 5, and 10 after planting. Stock-type and family interacted to affect height at year 1 on one site. There were no other interactions through 10 years. Container stock performed consistently better than bareroot at each interval measured. There were differences among half-sib families for diameter and height on both sites for some measurement periods. Family ranks for total height early in the experiment correlated with 10 year performance on both sites.
