The influence of climate on tree-ring maximum latewood density in norway spruce (Picea abies (L.) Karst.) at two sites in Slovenia | Vpliv klime na maksimalno gostoto kasnega lesa v branikah smreke (Picea abies (L.) Karst.) na dveh rastiscih v Sloveniji

Norway spruce (Picea abies (L.) Karst.) is frequently the object of dendrochronological research owing to its distribution, wood structure and longevity. The Norway spruce chronologies published in Slovenia so far have been based on tree-ring widths. This article presents the first density chronologies and describes the method of determining maximum latewood density (MXD). Two different sampling sites were selected (Pokljuka and Sorsko polje) and 13 sampling cores were taken from each site. The results showed positive correlation between MXD and temperatures in August and September. Furthermore,higher MXD values and less pointer years were observed at the lowland Sorsko polje site.
