Abstract
The effect of aluminium concentrations of 46, 70 and 140 ppm, respecti vely, on epicuticular waxes was studied in potted Picea abies (L.) Kar st. seedlings provided with nutrient solutions. There was a significan t decrease in Ca, Mg, and P concentration in the needles after a 10 mo nth period. Also chlorophyll fluorescence of needles was affected. How ever, no evidence of changes of epicuticular waxes was found due to Al toxicity when studying micromorphology of needles under the scanning electron microscope (SEM).
