Název v původním jazyce

Light induced regulation of excitation energy transfer during the development of barley photosynthetic apparatus under different irradiances.

Popis výsledku v původním jazyce

Effect of short-term exposure to high irradiance (1500 umol.m-2.s-1) on the transfer of excitation energy was studied during greening of barley plants at low (50 umol.m-2.s-1, LI) or high (1000 umol.m-2.s-1, HI) irradiances using 77K excitation spectra and room temperature modulated chlorophyll a fluorescence. The ability to down-regulate the efficiency of excitation energy transfer was inhibited for the HI plants grown under the intermittent light regime, due to the strong suppression of the accumulation of light harvesting complexes (LHC's) of both photosystems II and I. During greening under continuous light the ability to promptly regulate the excitation energy transfer within both photosystems was assessed from the light induced decrease of the excitation band attributed to the chlorophyll b and carotenoids (460-500 nm) in the 77K excitation spectra of Chl a fluorescence detected at 685 nm and 743 nm, respectively.
