Description	Dlouhodobé vystavení (23 týdnů) sazenic smrku ztepilého zvýšené intenzitě (+25%) ultrafialového-B (UV-B) záření v polních podmínkách vedlo k mírnému nárůstu koncentrace katechinu v jehlicích (ca 7%); zatímco u 4-hydroxyacetofenolu a piceinu byl pozorován signifikantní pokles (ca 80%, respektive 72%). Tato zjištění dokumentují, že UV-B záření indukuje rozdíly v syntéze specifických fenolických látek. V článku jsou diskutovány možné důsledky na změnu tolerance rostlin. (cs) The long-term (23 weeks) exposure of Norway spruce needles to supplemental (+25%) ultraviolet-B (UV-B) irradiances at field conditions resulted in the slight increase of catechin (ca 7%; p >0.05); however, significant decreases of extracted 4-hydroxyacetophenone (ca 80%; p <0.01) and picein (ca 72%; p <0.01). These findings document the dif-ferences in synthesis of specific phenolic compounds in-duced by UV-B radiation. The possible relations to plant tolerance are discussed.
