The influence of UV-B irradiation on the mitotic activity in Picea abies (L.) Karst.

Because of thinning of the ozone layer, there is a continual increase of ultraviolet B (UV-B) irradiation reaching the Earth. We have followed for two and a half years the influence of an artificial source of UV-B irradiation of 17685 J/m** 2 and 28010 J/m** 2 on spruce Picea abies (L.) Karst seedlings. The controls were irradiated with only normal, 6025 J/m** 2. Results show that 3 years seedlings are sensitive to irradiation, as may be first seen from their decreased mitotic activity and in lesser needle and seedling growth in their third year.
