Atmospheric CO2 concentration, light intensity and nitrogen nutrition affect spring barley response to drought and heat stress
Original language description
The aim of this study was to compare physiological responses of two spring barley varieties,ndiffering in their oxidative stress tolerance, to drought and heat stress after pre-treatment under differentnirradiation regimes, CO2 concentrations, and nitrogen fertilisation levels. High light intensity, elevatednCO2, and additional UV radiation increased flavonoid accumulation. Moreover, more flavonoids wereninduced in oxidative stress-sensitive variety Barke. Combined drought and heat stress caused a largendecline in CO2 assimilation, whereas heat stress alone caused only minor changes. Under combinednstress, plants grown under low light intensity and no UV irradiation performed the best despite theirnhigher initial water use efficiency and lower flavonoids content.
