Brief exposure of yeasts to low-intensity monochromatic light (400–730 nm) has revealed the effects of photoreactivation and photoprotection of the cells inactivated by medium wave UVB radiation (290–320 nm). The red spectral region with a maximum at 680 nm has been found to be the most active in the initiation of photoreactivation and photoprotection. It(More)
A method for estimating soil salinity is suggested. It uses parameters of plant fluorescence, based on the example of Meyer leadwort (Limonium meyeri), in order to develop methodology for monitoring changes in the plant-soil system. Use of the fluorescent method for investigation of the soil salinity problem can enhance the possibilities for information(More)
A biophysical methodical approach to the evaluation of soil status by the luminescence of humic substances and plants has been developed in order to create a conceptual basis for application of the method with express-monitoring of the soil status and for modeling of the ecological risk of the degradation processes. The use of optical methods to study the(More)
The effects of yeast cell photorecovery after photodynamic inactivation by optical radiation in the near-ultraviolet (320–380 nm) and visible (400–600 nm) ranges of the spectrum have been revealed. Red light at 680 nm has shown the highest efficiency and the maximum level of photoreaction upon short-term irradiation (minutes). For the first time, we show(More)
