A comparison of tree-ring features in Picea abies as correlated with climate

This paper presents an analysis of 16 anatomical variables measured on 20 s pruce trees [Picea abies CL.) Karst.] from sites in the managed forest dist rict Seyde, Eastern Ore Mountains, south of Dresden, Germany. Ring width an d latewood proportion did not show significant relationships with monthly c limatic data, whereas maximum density, latewood cell-wall proportion and la tewood density were highly correlated with temperature and precipitation. T he climatic signals expressed in resin duct density, ray height, tracheid l ength and microfibril angles were less pronounced. Of 16 tree-ring paramete rs, densitometry - as an indirect measure of xylem anatomy - has again show n its great potential to record climatic conditions.
