Effect of light conditions of wheat growing on sensitivity of photosynthetic machinery to salt stress

Effect of light conditions of wheat growing on sensitivity of photosynthetic machinery to salt... Sensitivity of wheat (Triticum aestivum L.) seedlings to salt stress was investigated as dependent on light conditions of plant growing. In two-week-old seedlings grown on salt-free medium, aboveground organs were detached from the roots and subjected to a brief stress at different concentrations of NaCl. The extent of salt stress effect expressed as a decrease in the rate of the photosynthetic release of oxygen and the relative content of water and chlorophyll in the leaves greatly depended on light conditions of growing. The plants grown at low light intensity were notable for a greater sensitivity to NaCl in the medium. Plant responses to salt stress were different at low and high salt concentrations. At low NaCl concentrations (0.05–0.10 M) in the solution, in plants grown at low light intensity, the rate of photosynthesis calculated per unit of chlorophyll increased. This effect was not observed in plants grown at the higher light intensity. At high NaCl concentrations (0.2–0.4 M) in the medium, the rate of photosynthesis rapidly decreased in all the types of treatment, with the effect being most pronounced in plants grown at low light intensity. The obtained results suggest a narrow range of NaCl concentrations with an optimum at 0.1 M positively affecting the wheat seedlings physiological state upon salt stress development depending on light conditions of plant growing. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals
