摘要

The purpose of the study was to determine which of four conifers--loblolly pine (Pinus taeda L.), shortleaf pine (P. echinata Mill.), Virginia pine (P. virginiana Mill.), and white pine (P. strobus L.)--would be the most desirable species for planting on poorer upland Piedmont sites where hardwood establishment is generally unsuccessful. The study reported here was undertaken to determine if the four pine species produced different forest floors, and if the trees modified the surface mineral soil to different extents. (Author)
