    Differences in the photosynthetic UV-B response between European beech (Fagus sylvatica L.) and Norway spruce (Picea abies (L.) K a r s t.) saplings

  • 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, thede-epoxidation 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.

    Rozdíly ve fotosyntetické UV-B odezvě mezi sazenicemi buku lesního a smrku ztepilého

  • Czech description

    Sazenice smrku ztepilého a buku lesního (stáří 7 let) byly vystaveny zvýšené dávce UV-záření (+25%) po dobu tří vegetačních sezón (1999-2001). Vybrané parametry variabilní fluorescence chlorofylu a a zastoupení pigmentů byly analyzovány na koci léta třetí růstové sezóny k ocenění vlivu dlouhodobého vystavení zvýšené UV-B radiaci. Tyto rostlinné druhy reagovaly odlišně k dlouhodobému působení zvýšené UV-B radiaci, smrk ztepilý byl více citlivý.
