    loblolly pine. This suggests that any variations in the virulence of the rust fungus have not affected the incidence of infection. Kinloch and Stonecypher () found no significant environmental effect on relative ranking of rust susceptibility among control- and open-pollinated loblolly pine families planted. A year-old stand of loblolly pine (Pinustaeda L.) in southeastern Oklahoma was thinned to three target basal-area levels: , , and 23 m 2 •ha −1 (control).Specific gravity, latewood percentage, date of transition from earlywood to latewood, growth, and climate variables were measured for 2 .

    Slash pine seeds from many sources have been grown in replicated provenance tests at several geographic locations (51,57). When north Florida- south Georgia seed sources were planted north or west of their natural range they did not survive planting or grow as well as trees from South Carolina or Louisiana . A study was conducted to identify geographical variation in loblolly pine bark and wood properties at the whole-tree level and to quantify the responses in whole-tree bark and wood properties following contrasting silvicultural practices that included planting density, weed control, and fertilization.

    Seed and Orchard-Container facility in Wedgefield. The longleaf pine seed sources were from South Carolina and Georgia. The im-proved loblolly pine seed sources were from the coast of South Carolina. The Pt bareroot seedlings were produced by applying vegetative inoculum at ox (volume)/linear foot of seedbcd (4 ft2) just prior to sowing. (4) A study of 14 full-sib families tested on two sites in South Carolina has evaluated genetic variation of several juvenile wood properties of loblolly pine: alpha-cellulose content, average fiber length, coarseness, and lignin content. The families differed significantly for all the chemical and morphological wood properties on both sites.

The significance of genetic variation in commercially important technological characters of wood has been realised only in the last 50 years: most of the initial studies were made by silviculturists and later by tree breeders, occasionally in cooperation with wood technologists rather than anatomists.

Abstract. Seed source testing of loblolly pine (Pinus taeda), which began in the s, has allowed large realized genetic gains from using nonlocal seed sources in operational source testing continues, and deployment guidelines are still being refined. Some general effects of seed source movement can be described, but there are still gaps in (1) understanding exactly how far.
