Health condition of young spruce stands growing in Poľana in different altitudes
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...

| Summary: | 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. |
