This study examines whether different monthly climatic parameters based on temperature and precipitation significantly influences radial growth and wood relative density of red pine (Pinus resinosa Ait.). Cores were sampled on trees originating from a plantation established at 4.3 x 4.3 m in Chalk River, Ontario, and were scanned on a X-ray densitometer. The following were measured on each ring: width and relative density relative densities of earlywood and latewood zones, minimal and maximal relative densities and latewood proportion. Significant relationships were derived for every dependent variable. Except for latewood relative density and maximum relative density, the independent variables that were significant consisted of previous and current year climatic variables based on mean temperatures, total precipitations, degree-days, number of days with precipitations and maximum number of continuous days without precipitation. These results indicate that wood formation of red pine is influenced by temperature as well as by the quantity and timing of precipitation.
