Description
  • Odezva sazenic smrku ztepilého (Picea abies [L.] Karst.) byla monitorována průběžně během krátkodobého vystavení (10 dnů) vysoké ozářenosti (1000 umol m-2 s-1). (cs)
  • The response of Norway spruce saplings (Picea abies [L.] Karst.) was monitored continuously during short-term exposure (10 days) to high irradiance (HI; 1000 umol m-2 s-1). As compared to plants acclimated to low irradiance (100 umol m-2 s-1), plants after HI exposure were characterized by a significantly reduced CO2 assimilation rate throughout the whole light response curve. Pigment contents varied only slightly during HI exposure, but a rapid and strong response was observed in the xanthophyll cycle activity, particularly within the first three days of the HI treatment. Both violaxanthin convertibility under HI and the amount of zeaxanthin pool sustained in darkness increased pronouncedly under HI conditions. These changes were accompanied by an enhanced non-radiative dissipation of absorbed light energy (NRD) and the acceleration of induction of both NRD and de-epoxidation of the xanthophyll cycle pigments.
