Abstract Seedlings of Livingston Parish (Louisiana) loblolly pine (Pinus taeda L.) have been widely used across the Gulf and south Atlantic Coastal Plain to reduce the damage caused by the fusiform rust disease. Since this seed-source material provided the first rust-resistant seedlings available to forestland managers, it was used wherever rust damage was heavy, in some cases into the Piedmont north of the recommended area of planting. This paper evaluates the performance of ten-year-old Livingston Parish trees in such an area. The rust resistance of the Livingston Parish trees was outstanding, with 83% being free of disease as compared with only 14% of the commercial controls. There was no difference in growth between the two groups of trees, and ice breakage was not significantly greater in the Livingston Parish trees. South. J. Appl. For. 10:84-87, May 1986.

Abstract In three separate studies on the Lower Atlantic Coastal Plain, sites were sheared, root-raked, and bedded, and phosphorus was applied. Loblolly pine (Pinus taeda L.) seedlings were planted, and nitrogen fertilizer and preemergence herbicide were applied at several different times. In all three studies, loblolly pine responded positively in height, diameter, and aboveground biomass to herbicide applied in the spring following planting. Responses to nitrogen application were inconsistent. A pronounced increase in growth was found in only one study. There, a nitrogen and a herbicide treatment interacted to give a three-fold increase in aboveground seedling biomass after one growing season. The lack of response to nitrogen in the other two studies may be attributable to low rainfall in the spring after planting and mineralization of native nitrogen from soil organic matter. South. J.

Abstract Growth response of loblolly pine (Pinus taeda L.) to bedding and phosphorus fertilization was determined on three sites classified as moderately well, somewhat poorly, and poorly drained. Ten-year growth in terms of height and diameter showed a pronounced response to treatments on the poorly drained site but only a small response on the other sites on which competition was eliminated as a factor in all treatments. Bedding and fertilization interacted only on the poorly drained site where response to bedding was most pronounced. Our projection of height over age curves for individual treatments suggest that response to phosphorus alone may compare favorably with bedding plus phosphorus after the pines are about age 20 on the poorly drained site. Nutrient concentration in foliage alone was not indicative of the differential growth response to fertilizer obtained over drainage classes.

Abstract Sample size is tabulated for the number of tree heights needed to site-classify plots growing natural, Atlantic coastal plain loblolly pine (Pinus taeda L.). The size of the sample depends on observed stand age and selected site-class size, index age, and classification success rate. The most important outcome is the relationship of sample size to stand age because putting it into practice results in uniformly reliable site-index estimates.

Abstract Thirteen traits were evaluated on 131 Sonderegger (Pinus x sondereggeri Chap.) and 69 loblolly pine (Pinus taeda L.) trees within two 20-year-old mixed pine plantations located in the South Carolina upper coastal plain. Of the traits measured, bark thickness was found to be slightly greater in Sonderegger pine and branch angle more acute in loblolly pine. No difference was found in height, d.b.h., or volume between the two species. However, considerable variation was observed within each species for most traits. Fusiform rust damage on Sonderegger boles did not differ in severity from that observed on loblolly pine. Highly vigorous trees of the hybrid showed no more susceptibility to fusiform rust than did less vigorous trees. On an index scoring basis, several trees of Sonderegger pine were found that might quality for a southern pine breeding program. From these results, we see no reason to discriminate against Sonderegger pine in thinnings and other stand management practices when it occurs with other pines on similar sites in the southeastern United States.

Loblolly pine (Pinus taeda L.) is a major plantation species grown in the southern United States, producing wood having a multitude of uses including pulp and lumber production. Specific gravity (SG) is an important property used to measure the quality of wood produced, and it varies regionally and within the tree with height and radius. SG at different height levels was measured from 407 trees representing 135 plantations across the natural range of loblolly pine. A three-segment quadratic model and a semiparametric model were proposed to explain the vertical and regional variations in SG. Both models were in agreement that a stem can be divided into three segments based on the vertical variation in SG. Based on the fitted models, the mean trend in SG of trees from the southern Atlantic Coastal Plain and Gulf Coastal Plain was observed to be higher than in other physiographical regions (Upper Coastal Plain, Hilly Coastal Plain, northern Atlantic Coastal Plain, and Piedmont). Maps showing the regional variation in disk SG at a specified height were also developed. Maps indicated that the stands in the southern Atlantic Coastal Plain and Gulf Coastal Plain have the highest SG at a given height level.

In an extensive series of trials with open-pollinated families of loblolly pine (Pinus taeda L.), resistance to fusiform rust disease (caused by Cronartium quercuum (Berk.) Miyabe ex Shirai f. sp. fusiforme) at individual test sites was relatively unpredictable for the families deemed most resistant. The most resistant families were also the most stable for performance across test sites, with stability defined as the slope of the regression of family means for rust infection versus site means for rust infection. A family's R-50 value (its predicted rust infection level when the site mean infection is 50%) was correlated to its stability parameter or slope (r = 0.78). On average, any one family's level of infection (% galled) was reasonably predictable for any given infection level at a given site; the average coefficient of determination (r2) was 0.78 for the regression of family means for rust infection versus site means for rust infection. However, the six most stable families for resistance had the lowest r2 values (average r2 = 0.58). We speculated that the lower predictability for the most resistant families was due to interactions of specific resistance genes in these families and corresponding avirulence and (or) virulence levels in the pathogen populations that may differ among sites. Although the predictability of the individual resistant families was relatively low, if these families were bulked into a resistant seed lot, they performed in a more predictable manner with r2 = 0.74 for the regression of the bulk mean versus site means. Bulks of four to six highly resistant families appeared to be a good solution to obtain stable and predictable performance across a range of sites.

Abstract Five surveys of pine plantations in East Texas over an 18-year period (1969-1987) indicated that fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme Birdsall and Snow) infection rates have increased to current levels of about 50% on slash pine (Pinus elliottii Engelm.) and are continuing to increase on loblolly pine (Pinus taeda L.) to 10-15% levels.
