Abstract Unthinned, pole-size loblolly pine (Pinus taeda L.) plantations in the South Carolina Piedmont were burned at different seasons under minimal wind conditions to evaluate the effects of fire intensity on crown scorch. Needle drop, an indicator of crown scorch, was significantly greater on areas burned with medium- to high-intensity fires than on unburned plots. There was a direct relation between bark char height, beyond a threshold value of 3 feet, and crown scorch. Scorched needles fell within three weeks following fire. Moderate crown scorch had no detrimental effects on survival and growth of trees in the upper crown classes. Complete crown scorch resulted in the death of 20 and 30 percent of trees in the codominant and intermediate crown classes, respectively.

Abstract In a comparison of three diverse seed sources of improved Virginia pine (Pinus virginiana Mill.) planted at two locations in north Alabama and south-central Tennessee, only stem straightness differences were statistically significant at six years of age. Families and seed sources tended to maintain the same ranking relative to each other at both locations. A majority of families performed significantly better than a Virginia pine commercial check lot, indicating substantial improvement in growth and straightness characteristics in one generation of selection. Two improved loblolly pine (Pinus taeda L.) seed orchard mixes from the South Carolina Piedmont showed a 27-percent height advantage over the Virginia pine at age 6.

Pinus Taeda L

Abstract Prescribed burning of young unthinned plantations of loblolly pine (Pinus taeda L.) in the South Carolina Piedmont significantly reduced the quantity of individual nutrients in the L layer, but not the F + H layers of the forest floor. Burning reduced the weight of the L layer by 60 percent but the weight of the combined F + H layers was unaffected by the relatively fast-moving strip-head fires. Nutrient losses by ash convection from the L layer during the prescribed fire ranged from 3.6 lbs/ac for P to 23.1 lbs/ac for N. Some impaction of nutrients released in burning on pine canopies was detected by analysis of throughfall and stemflow. However, quantities of nutrients intercepted and released by the canopy are small when compared to nutrient transfer by leaf fall and precipitation. The canopy and stems markedly altered the nutrient concentrations of intercepted precipitation.

Abstract Container-grown loblolly pine seedlings (Pinus taeda L.) with Pisolithus tinctorius, Thelephora terrestris, or no ectomycorrhizae (control) were outplanted on a South Carolina reforestation site. Two years after planting, seedlings initially colonized with Pisolithus or Thelephora had greater survival, height, and root collar diameter than control seedlings. Growth data were integrated into seedling volume indices (D²H). Seedlings with ectomycorrhizae at planting had nearly a three-fold greater D²H than seedlings initially without ectomycorrhizae. These results provided additional field validation for the hypothesis regarding benefits of ectomycorrhizae on this type of planting stock.

Abstract The performance of adjacent unthinned plantations of loblolly (Pinus taeda L.) and slash pine (P. elliottii Engelm.) on three sites in South Carolina was evaluated after 16 growing seasons. Sites ranged from a noneroded Piedmont soil to an excessively drained sandy soil of the Sandhills physiographic region. Growth and survival varied widely among sites, with greatest productivity occurring in the Piedmont and the lowest in the Congaree Sandhills. Despite the droughty nature of the latter site, survival after 16 growing seasons was over 80 percent for both species. On a volume basis, loblolly pine outperformed slash pine at the upper Pidemont and Aiken Plateau sites, while slash pine was superior on the dry Sandhills site. Incidence of fusiform rust was much higher for both species at the Aiken Plateau than at the other sites.

Abstract Various levels of crown scorch on 19-year-old loblolly pine (Pinus taeda L.) were examined. Scorching and mortality were greatest for small-diameter, suppressed trees. Diameter growth one year after scorching was not diminished for lightly scorched trees but decreased with increasing crown scorch. During the second and third growing seasons after scorching, only trees receiving complete crown scorch exhibited significantly less diameter growth. South. J. Appl. For. 11(4):209-211.

Abstract A 5,900 acre poorly drained watershed on the South Carolina coast is being converted from natural hardwood forest to loblolly pine (Pinus taeda L.) plantation. Water samples were collected at 20 sampling points after each of 14 rainstorms during a 2-year study period. Dissolved oxygen and pH levels were slightly higher in the plantation drainage than in the hardwood drainage, but overall water quality was not significantly changed by the conversion process. South.

Abstract Surface drainage created adequate conditions for survival and growth of loblolly pine (Pinus taeda L.) on most sites within a wet lowland area. Successful pine establishment occurred on soils having loamy or sandy surface horizons and where original forest cover had been pine-hardwood or hardwood. On a lesser but significant number of sites, however, loblolly pine had unsatisfactory survival. Such problems were common where clay content of surface soil was high and the water table remained near the surface after ditch installation. In most cases, these conditions occurred on sites formerly occupied by cypress-hardwood timber. Planted sweetgum (Liquid ambar styraciflua L.) and baldcypress (Taxodium distichum (L.) Rich.) had better survival than loblolly pine on these sites. Guidelines for delineating such problem sites are given and management alternatives discussed.

Abstract A new cubic volume equation was developed for plantation grown loblolly pine (Pinus taeda L.) in Coastal Plain and Piedmont regions of Georgia and South Carolina. This volume equation uses the volume of the main stem between 2.25 and 5.00 ft as the independent variable. In practice, users simply need to measure diameters at 2.25 and 5.00 ft from the ground to obtain an estimate of the total cubic foot volume of the main stem. This new equation compares favorably to traditional volume equations which use dbh and total height as independent variables. South. J. Appl. For. 17(3):160-162.

Pinus Taeda L

We studied the effect of water availability on basal area growth and wood properties of 11-year-old loblolly pine ( Pinus taeda L.) trees from contrasting Florida (FL) (a mix of half-sib families) and South Carolina coastal plain (SC) (a single, half-sib family) genetic material. Increasing soil water availability via irrigation increased average whole-core specific gravity (SG) and latewood percentage (LW%) by 0.036 and 6.93%, respectively. Irrigation did not affect latewood SG or wood stiffness, but irrigated FL and SC trees had more latewood due to a 29 day longer growing season. Irrigation did not affect the length of corewood production, but irrigated trees had earlier transition ages, producing outerwood ~3 years before rainfed trees. The increase in whole-core SG and LW% was moderate because irrigation promoted earlywood growth in corewood formed before canopy closure, but after year 7, rain-fed and irrigated trees had similar earlywood growth but irrigated trees had more latewood growth, increasing ring SG and LW%. The SC half-sib family had higher SG and greater LW% than trees from FL independent of irrigation due to greater yearly latewood growth. Thus, absence of soil water stress extended seasonal diameter cessation date but did not change latewood SG or wood stiffness.
