Response of epidermal blue-green fluorescence emission from Barley leaves to uv radiation stress

Popis výsledku v původním jazyce

Blue-green fl uorescence (BGF) is emitted by plant tissue when excited by UV radiation. Th e emission spectrum of BGF varies with plant species and is aff ected by the physiological status of the plant. BGF has been attributed mainly to cell wall-bound ferulic acid, although a contribution from fl avonoids and other simple phenols has also been suggested. Th e BGF signal is of interest due to its potential application in the remote sensing of plant stress: such techniques use ratios of blue and green tochlorophyll red and far-red fl uorescence emission intensities to estimate plant stress. In this work we investigated the response of BGF to UV-radiation stress and characterized changes in the shape of BGF emission spectra. We found these changes to bemore signifi cant during the acclimation to UV-B radiation in comparison with UV-A or high irradiance of PAR. Furthermore, the spectral changes in BGF emission were due to a decline of fl uorescence at a wavelength of 435 nm compared wit
