Basic density and absorbed energy in impact bending were measured for 500 Norway spruce ( (L.) H. Karst.) samples from Northern and Southern Finland. Statistical analysis showed that the relationship between impact strength and basic density was significant and regression analysis showed that it was linear.Picea abies
