We evaluated the seasonal dynamics of wood formation in Norway spruce during 2002-2004 using the Gompertz function. The number of xylem cells reflects cambial productivity, while xylem increment also includes radial expansion of the newly formed tracheids. Comparison of the parameters of the Gompertz function obtained from cell numbers and from measured widths revealed minor differences in the values, but they were not statistically significant. Measurement of the xylem increment is faster than cell counting and might be more appropriate for studying deciduous trees.

The Norway spruce chronologies published in Slovenia so far have been based on tree-ring widths. In this paper we presents the first density chronologies and describes the method of determining maximum latewood density (MXD). 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 Sorško polje site.
