Powers, Jr, H R

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. (PSB)
