Abstract:Response of height growth of red pine (Pinus resinosa Ait.) to changes in climatic conditions was analyzed using data collected in a 48-year-old provenance trial established in northwestern Ontario, Canada. Seed sources for the trial were collected from 23 provenances spanning the natural range of red pine. Mean monthly values of climatic variables were estimated from historical climatic data for 1971 to 2000. Quadratic transfer functions predicting mean tree height at age 48 and tree top height at age 50 were… Show more
