Abstract
The influence of an artificial source of UV-B irradiation of 21.2+/-3. 4 kJ/m(2) and 32+/-2.5 kJ/m(2) on Norway spruce (Picea abies (L.) Kars t.) seedlings has been under observation for two and a half years. The controls were irradiated with normal 11.7+/-5.2 kJ/m(2). The results show that 3 year old seedlings are sensitive to irradiation, as can be first seen from their decreased mitotic activity and lesser vitality.
