Physiological significance of proline and glycinebetaine: Maintaining photosynthesis during NaCl stress in wheat

Year: 1997

Type: article

Abstract: Experiments on the physiological significance of accumulation of proline and glycinebetaine (GB) in sustaining photosynthesis during salt stress in wheat in vivo showed that pre-treatment with GB, but not proline, alleviated NaCl-induced stomatal and non-stomatal inhibition of photosynthesis completely. A permeating and non-dissociating osmoticum, 3-orthomethyl-glucopyranose, also alleviated NaCl-induced perturbations of photosynthesis, suggesting that GB may work by maintaining chloroplast volume and not by specific effects on photosynthetic processes.
