Differences in the photosynthetic UV-B response between European beech (Fagus sylvatica L.) and Norway spruce (Picea abies (l.) Karst.) samplings

Original language description

Cloned saplings of Norway spruce (Picea abies (L) K a r s t.) and beech (Fagus sylvatica L.) (7 years old) were exposed to enhanced UV-B irradiation (+25%) continuously over three growing seasons (1999-2001). Selected parameters of variable chlorophyll afluorescence and pigment composition were analysed in the late summer of the third growing season to evaluate the influence of long-term elevated UV-B irradiation on broadleaf and conifer tree species. To obtain information on the xanthophyll cycle, thedeepoxidation state (DEPS) was calculated. These tree species responded differentially to the long-term effects of enhanced UV-B radiation, Norway spruce was more sensitive compared to the European beech. The results show that in Norway spruce a long-term exposure to enhanced UV-B radiation under field conditions caused negative changes at the level of primary photosynthetic reactions. Contrary to the beech, this had higher degree of UV-B protective responses. UV-B radiation is not effe
