Electron and proton transport in wheat exposed to salt stress: is the increase of the thylakoid membrane proton conductivity responsible for decreasing the photosynthetic activity in sensitive genotypes?

Popis výsledku v původním jazyce

Effects of salinity caused by 150 mM NaCl on primary photochemical reactions and some physiological and biochemical parameters K+ vers. Na+ ratio, soluble sugars, proline, MDA have been studied in five Triticum aestivum L. genotypes with contrasting salt tolerance. It was found that 150 mM NaCl significantly decreased the photosynthetic efficiency of two sensitive genotypes. The K+ vers. Na+ ratio decreased in all genotypes exposed to salinity stress when compared with the control. Salinity stress also caused lipid peroxidation and accumulation of soluble sugars and proline. The amounts of soluble sugars and proline were higher in tolerant genotypes than sensitive ones, and lipid peroxidation was higher in sensitive genotypes. The noninvasive measurements of photosynthesisrelated parameters indicated the genotypedependent effects of salinity stress on the photosynthetic apparatus. The significant decrease of chlorophyll content SPAD values or adverse effects on photosynthetic functions at the PSII le
