Growth performance of loblolly shortleaf, and pitch X loblolly pine hybrid growing along the western margin of commercial pine rangeThis article is part of a larger document. View the larger document here.
Expansion of the commercial pine range is one of the opportunities to improve forest production and counterbalance the loss of forest land to other uses. The potential genotypes for the purpose are fast-growing loblolly pine (Pinus taeda L.), the slower growing, but more drought tolerant shortleaf pine (P. echinata Mill.), and the more cold tolerant pitch x loblolly pine hybrid (P. rigida x taeda). An uncertainty regarding the effect of potential climate change on the future commercial range of pine plantation also calls for the detailed information on survival and growth performance among the potential genotypes planted at the margin of the range.
