Provenance ranking for a earlywood density (g. cm−3) at each site, b basal area at 30 years old (cm2) at each site, c growth index (%) in Félines for the 2 dry years 2003 and 2004, and d growth index (%) in Le Treps for the 2 dry years 2003 and 2004. P.val corresponds to the probability value of the significant provenance effect for each site, tested by a single-effect variance analysis. The vertical lines illustrate the non-significant difference among provenances assessed by a Duncan test. Boxed codes indicate the IUFRO code of provenances, colours indicate different geographical origins: black for Californian and Oregon coastal provenances, grey for south interior provenances, white and dashed gray for northern provenances from British Columbia
