Comparison of shortleaf pine x loblolly pine F1 hybrid physiology and morphology to parent open-pollinated offspring

Hybrids between shortleaf pine (Pinus echinata Mill.) and loblolly pine (Pinus taeda L.) previously were more frequent in drought and fire prone areas west of the Mississippi River (Hare and Switzer 1969; Edwards-Burke and Hamerick 1995; Tauer et al. 2007; Raja et al. 1997; Stewart et al. 2011 unpublished). However, recent evidence indicates that hybrids have been increasing at an alarming rate since the 1950’s throughout the southeastern US (Stewart et al. 2011 unpublished). The goal of this study was to compare the physiology and morphology of artificial hybrids to those of the parent populations to determine whether shortleaf pine x loblolly pine hybrids might inherit useful traits from their parent species that have allowed them to thrive and increase in abundance over the past 60 years.
