Abstract The performance of container and bareroot loblolly pine (Pinus taeda L.) seedlings from the same improved seedlot was compared on highly productive bottomland sites in South Carolina. At the time of planting, size and quality of the open-grown container stock were equal to or betterthan bareroot material. When outplanting conditions were ideal, field plantings in March, April, and May of 2 successive years indicated equal performance of the 2 stock types. When conditions were more stressful, container stock survived and grew better than bareroot seedlings. Needle-tipburn caused by postplanting applications of herbicides had no long-term effects on seedling growth. South. J. Appl. For. 17(2):80-83.

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.

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 Loblolly pine (Pinus taeda L.) seedling height (measured immediately following planting) was significantly related to survival after two growing seasons. This relationship was negative on sites classified as adverse, with shorter seedlings having better survival than taller ones. Onnonadverse sites, taller seedlings survived as well or better than shorter seedlings. On all sites, initial height was inversely related to total seedling height growth during the first two seasons, permitting shorter seedlings at planting to reach the same total height as taller ones by agetwo. As a result, at age two, initial field height was not significantly related to total height. South. J. Appl. For. 11(3):139-143.

Pinus Taeda L

A Longidorus species was consistently associated with patches of stunted and chlorotic loblolly pine seedlings at a forest-tree nursery in Georgia. Seedlings from affected areas had poorly developed root systems that lacked lateral and feeder roots. Longidorus population densities in composite soil samples from the margins of patches ranged from 9 to 67 nematodes per 100 cm3 of soil. In a growth chamber experiment, seedling root dry weight decreased with respect to the initial Longidorus dose as well as the final Longidorus populations in containers. The dry root weight of seedlings were 0.117, 0.090, 0.066, and 0.065 g in containers initially infested with 0, 50, 100, and 200 Longidorus, respectively. Lateral and fine roots were lacking on seedlings at the highest doses. Populations of Longidorus increased in all containers during the experiment. Damage to loblolly pine seedlings caused by Longidorus is a previously undescribed problem in southern pine nurseries. Proper diagnosis of the problem by nematode testing laboratories may require the use of extraction techniques specific for larger nematodes such as Longidorus.

Abstract Twenty-four machine-planted stands of loblolly pine (Pinus taeda L.) of ages 3 to 10 yr were sampled near Athens, GA, to compare stem sinuosity, tree size, and pest injury of trees with bent versus straight taproots. Based on a 0- to 8-point index, the average level of stem sinuosity was medium (X = 2.6; n = 1,327 trees). Trees of high or low stem sinuosity index were identified near each of ten points per site, and one was selected to best represent each level (n = 240 pairs). Seventy-two pairs were excavated, and of these, 62 and 82 trees had bent and straight taproots, respectively. Levels of stem sinuosity were medium or high for 77% of trees with bent taproots, while they were low for 71% of trees with straight taproots (chi-square P = 0.001). Trees with bent taproots were 7% to 9% smaller in stem diameter and height, while their stem sinuosity index was over twice that of trees with straight taproots (P = 0.01). Taproot azimuth did not differ significantly (P > 0.20) from planting row azimuth, indicating that bent taproots from machine planting remained confined to the planting slit. Although biological mechanisms were not identified, results indicate a potentially problematic association between bent taproots and reduced stem quality of loblolly pine. South. J. Appl. For. 23(4):197-202.

Abstract Control-pollinated polymix progenies of 9 slash pine (P. elliottii Engelm.) and 10 loblolly (Pinus taeda L.) pine from some of the best clones in a South African tree improvement program were tested in Georgia. Overall, the progenies of the South African selections in both species have done well after five years in the field. One of the slash pine and three of the loblolly pine families were better than open-pollinated progeny from established seed orchards.

Growth Of Seedlings

Abstract Loblolly pine (Pinus taeda L.) seedlings were lifted from two nurseries in Georgia, and the roots were washed using equipment built for that purpose. Seedlings then received two levels of storage and were outplanted not far from the nursery of origin (one loam soil and one sandy soil). Immediately after washing, root weights and the length of fine roots did not differ among wash treatments from either nursery. Survival was excellent for all treatments on the loam soil, but a single wash reduced survival by 5 to 10% when seedlings were planted in sand. Washing slowed the rate of budbreak and early height growth. Bud growth of seedlings planted in a stress pit (containing sand) was correlated with both root growth 1 month after planting (r = 0.36,P = 0.0003) and survival 2 months after planting (r =0.62,P = 0.01). Among seedlings outplanted on a sandy site, initial height growth also correlated with survival (r = 0.49,P = 0.007). South. J. Appl. For. 25(1):25–30.
