Loblolly Pine Provenance Test at Age 35
Abstract:A plantation of 35-year-old loblolly pine (Pinus taeda L.) at Bogalusa, La., from four geographic sources varied at the 1-percent level of significance in height, diameter, individual-tree volume, and volume per acre, and at the 5-percent level in survival and in percentage of living trees trunk-infected with fusiform rust. The plantation contained 5,899 board feet per acre by International ¼-inch rule, 84 percent in trees of Louisiana origin. The plantation constitutes the first replicated provenance test of any southern pine known to have completed a 35-year pulpwood rotation, and the final survivals, heights, diameters, volumes, and degrees of rust infection indicate that conclusions drawn from such tests at 10 or even at 20 year may be premature.
