Abstract: This paper presents the first results of chlorophyll fluorescence measurements on assimilatory apparatus of Norway spruce. Three young spruce stands located in various altitudes (600, 1,050 and 1,250 m above sea level) were selected for the measurements. Chlorophyll fluorescence a was measured by a portable fluorimeter PEA. These measurements were performed on three needle year-classes. We found greater stand damage on the areas which are located in higher altitudes, but only at the end of growing season.
