| Description
| - 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 to chlorophyll 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 be more 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 with bands around 455 nm and 520 nm. In view of this, we have tried to distinguish individual fl uorescent components using more detailed fl uorescence analysis and to explain the causes of these spectral changes.
