The relationship of N, P and K availability to fusiform rust incidence in a resistant and a susceptible family of slash pine was examined in greenhouse pot ...
Publication Correlations Between Controlled-Environment and Nursery-Grown Seedlings of Jack Pine Provenances
Estimates of genetic variation can be obtained from tree seedlings grown in a uniform environments If sound predictions of adult performance can be made ...
Publication Optimum pH for Growing Pine Seedlings
Two schools of thought address the optimum soil pH (measured in water) for growing pine seedlings (Pinus spp.) in bareroot nurseries. One school uses ...
Publication Predicting genetic parameters and tolerance to pitch canker in slash pine
Pitch canker is an increasingly important threat to Southeastern forests, especially in slash pine (Pinus elliottii var. elliottii Engelm.). Its increasing ...
Publication Female Strobili on 12-Month-Old Jack Pine
Forest geneticists and tree breeders are continuously searching for ways to reduce the age at which flowering begins. Jack pine (Pinus banksiana Lamb.) is ...
Publication Lammas Shoot Formation in Scotch Pine
Lammas shoots are second or midseason shoots that develop precociously from buds set earlier in the season (5). These precociously developed shoots ...
Publication Identification of Candidate Interacting Resistance and Avirulence Genes in the Fusiform Rust Pathosystem
Fusiform rust is a disease incited by the fungus Cronartium quercuum f.sp. fusiforme (Cqf) on southern pines (where it causes galls on stems and branches) and ...
Publication Rectangular Spacing: An Economic Benefit?
Many loblolly pine (Pinus taeda L.) plantations are established at row spacings of 8 to 12 feet, but some compa-nies are now using rows spaced 14 to 18 feet ...
Publication Jellyrolling May Reduce Media Use and Transportation Costs of Polybag-Grown Seedlings
Growing medium and transportation are major costs for polybag nursery systems. Both could be reduced if the medium could be removed for reuse, and the ...
Publication Factors Contributing To Genetic Variation In Ice Damage Susceptibility In Shortleaf
There are differences among species in susceptibility to ice damage (Williston 1974). There is also at least one report on within-species variation, where ...
Publication Hardwood Cover Crops: Can They Enhance Loblolly Pine Seedling Production
It has been extremely difficult to obtain more than two loblolly pine (Pinus taeda L.) crops following even effective soil fumigation with methyl bromide in ...
Publication Early Selection of Loblolly Pine Families Based on Seedling Shoot Elongation Characters
Seedlings of 23 open-pollinated loblolly pine (Pinus taeda L.) families and three checklots were grown in a greenhouse under two nitrogen ( N) levels (5 and ...

Publication Genetic diversity in conifer stands: Evaluation, maintenance and improvement
Maintaining an "optimum" level of genetic diversity is often espoused as a reason to avoid plantation forestry as it is commonly practiced in the Southeast. ...
Publication Ectomycorrhizal Colonization and Intraspecific Variation in Growth Responses of Lodgepole Pine
Across different host plant species, the effects of mycorrhizal colonization on host growth parameters can vary, but intraspecific variation in ...
Publication Four Native Species and Two Hybrid Pines Compared in Western Maryland
The growth rates and survival of four pines native to Maryland ( Pinus taeda , P. strobus , P. rigida and P. virginiana ) and two hybrid pines (P. rigida x ...
