Влияние УФР на фотодинамические характеристики переменной флуоресценции хлорофилла меристемных регенерантов картофеля (Solanum tu-berosum)

Abstract

The effect of artificial ultraviolet radiation (UVR) on the complete chlorophyll-a fluorescence oscillation transients of the potatoes leaves was monitored using the basic parameters of the fluorescence induction curve. Some spring questions of the role UVR in the structural and functional regulation of plant cells metabolism are considered and analysis is made of possible mechanisms of transformations of the low UV-radiation levels in them. The results of this study indicate that the different physiological and biochemical factors contribute toward potatoes plants sensitivity to UV-radiation
