We present some results of ecophysiological measurements (chlorophyll a fluorescence, concentration of assimilatory pigments, concentration of mineral nutrients) by means of which we assessed the health state of spruce advanced regeneration in the area of the Kysucke Beskydy Mts., Slovak Republic. We focused on determining the cause of assimilatory organs' yellowing and of different responses of advanced regeneration stands growing in equal site conditions. The results of ecophysiological measurements depended on the age of the trees, their health state and on the season.
