Comparing First-year Growth of Bare-Root and Container Plantings of Shortleaf Pine Half-Sib Families

Shortleaf pine seeds were collected from several ramets of clones identified as the female parents of seedlings that were either relatively good or relatively poor survivors in fullsib progeny tests. Seedlings from six such half-sib families were grown as both bare-root and container stock and planted on two sites in the Ouachita Mountains of Arkansas. When outplanted, the bareroot seedlings had greater mean height and root collar diameter than the container seedlings. However, the container seedlings had greater mean root volume and a more favorable shoot-to-root balance than the bare-root stock. After one growing season in the field, survival of all the families from both stock-types exceeded 94% at both locations. The container seedlings grew larger than the bareroot seedlings on both sites. Among the families, groundline diameters differed on one site, and family and stock type interacted in their effects on height on the other site.
