| Description
| - Divoký typ (WT) ječmene jarního a jeho mutant bez Chl b chlorina f2 (clo f2) rostoucí ve stinných podmínkách ve skleníku byly přeneseny na přímou sluneční radiaci v červnu s převážně jasnými dny. Během 6 dnů po přenesení rostlin jsme sledovali obsah fotosyntetických pigmentů, funkční stav fotosystému II (PSII) a účinnost epidermálního UV-stínění. Clo f2 byl více citlivý na vystavení zvýšené sluneční radiaci než WT. Nicméně, jak clo f2 tak WT byly schopny se přizpůsobit těmto stresujícím podmínkám, a to díky okamžité fotoprotekci zprostředkované karotenoidy (zvýšený obsah karotenoidů a zvýšená tepelná disipace lokalizovaná ve světlosběrných komplexech PSII). Bylo zjištěno, že míra epidermálního UV-stínění se zvýšila po přenesení rostlin a dosáhla saturační úrovně po 3 dnech. (cs)
- The wild-type barley (WT; Hordeum vulgare L.) and its chlorophyll (Chl) b-less mutant chlorina f2 (clo f2) grown under shaded conditions in a greenhouse were transferred to outdoor conditions in early June with predominantly bright sunny days. During 6 days following transfer of plants we monitored the content of photosynthetic pigments, functional state of photosystem II (PSII) and epidermal UV-shielding efficiency. Clo f2 mutant was more sensitive to exposure to an enhanced natural solar irradiance than WT barley. Nevertheless, clo f2 as well as WT were able to cope with stressful outdoor conditions. This was due to the immediate carotenoid-mediated photoprotection, reflected by strongly increased total carotenoids content and thermal energy dissipation localized within light-harvesting complexes of PSII. We found that for both WT and clo f2 epidermal UV-shielding increased clearly after transfer to outdoor conditions and reached a saturation level after 3 days.
