<abstract xmlns="http://www.w3.org/1999/xhtml">This research presents the variability in the survival and growth for 27 provenances of spruce (<italic>Picea abies</italic> (L.)

Growth rates of provenances were correlated with their geographical coordinates and climatic characteristics. Data was expressed in standard deviation units to select the best in growth provenances.Despite the significant differences in the location of the original stands (up to 12º N and 37º E), variability in survival, height and diameter is low (coefficient of variation is 12.2–19. 0%).
