Description
  • Pro jehličnany je klíčovým procesem při aklimaci na zvýšenou ozářenost nárůst účinnosti nezářivé disipace energie (NRD) v rámci PS II a to jak v laboratorních tak v přírodních podmínkách. Jehlice smrku ztepilého aklimované na vysokou ozářenost vykazují výrazné zrychlení indukce NRD a vyšší účinnost de-epoxidace violaxantinu (přibližně 90%) než je obvyklé pro ostatní rostlinné druhy s odpovídající velikostí xantofylového poolu a LHC II (poměr Chl a/b). Znalost dynamiky těchto procesů je nicméně nedostatečná. Proto jsme se zaměřili na vztah mezi kinetikou indukce NRD a de-epoxidací violaxantinu na zeaxantin během aklimace smrku na vysokou ozářenost.

  • For conifers the enhanced efficiency of non-radiative energy dissipation (NRD) within PS II is supposed to represent a key process of acclimation to elevated irradiance under both laboratory and field conditions. The needles of Norway spruce acclimated to high irradiance exhibit considerable acceleration of NRD induction and significantly greater efficiency of violaxanthin de-epoxidation (approximately 90%) than is usual for other plant species with corresponding xanthophyll cycle pool size and LHC II size (Chl a/b ratio). Nevertheless, knowledge of dynamics of these processes is insufficient. Therefore we focused on the relation between kinetics of NRD induction and de-epoxidation of violaxanthin to antheraxanthin and zeaxanthin during acclimation of Norway spruce to high irradiance.
