After winter 1995/96 the assimilatory apparatus of spruce Picea abies was heavily damaged in the region Ore Mts. The destruction of needles was analysed by evaluating the changes of epicuticular wax structure with the help of SEM and quantitative determination of waxes. The most intensive wax degradation and the lowest amount of wax on needles was evident at the highest altitudes. Assimilatory upparatus was not damaged at Picea pungens. In the control stands in regions with minimal pollutant load there were no destructive changes of epicuticular waxes even in the highest altitudes.
