Evaluation of Five Geographic Sources of Loblolly Pine to Environmental Stress Such as the Air-Borne Disease Organism Cronartium Quercuum F. Sp. Fusiforme, and Testing for Concentrations of Specific Elements in Diseased Tissue. Pr

摘要

Data were taken at the end of the third growing season on the 1920 seedlings representing the four geographic seed sources of loblolly pine being evaluated. Information was obtained on survival, those infected with fusiform rust, and height. In addition to these four different seed sources, these plots also include seedlings from a rust resistant orchard of both loblolly and slash pines, and susceptible Georgia slash pines, for a total of 3360 seedlings. The results show excellent survival rates with a fusiform rust infection level too low to draw meaningful conclusion after only three years. Height was a significant variable. (ERA citation 08:010752)
