In our study we demonstrate that high amount of blue light
triggers specific biochemical and physiological processes resulting
in better acclimation and recovery of plants to UV stress. Amongst
others this was clearly proven by gas exchange and fluorescence
measurements. UV induced degradation of photosynthetic related
pigments (chlorophyll a and b, as well as carotenoids) was stronger
in those plants cultivated either under lower light intensity or
lower amount of blue light, whereas plants grown either under
300 mol m−2 s or 62% blue light accumulated more epidermal
flavonols.
