Journal ArticleDOI
Photosynthesis and activity of superoxide dismutase, peroxidase and glutathione reductase in cotton under salt stress
TL;DR: In this article, the effects of NaCl stress on the activity of antioxidant enzymes such as superoxide dismutase (SOD: EC 1.15.1), peroxidase (POD:EC 1.11.7), and glutathione reductase (GR: EC1.6.4) were investigated in two cotton cultivars, Guazuncho and Pora, grown in nutrient solution.
Journal ArticleDOI
Solute accumulation and distribution during shoot and leaf development in two sorghum genotypes under salt stress
Claudivan Feitosa de Lacerda,José Cambraia,Marco Antonio Oliva,Hugo Alberto Ruiz,José Tarquinio Prisco +4 more
TL;DR: It is suggested that the reduction in shoot development and leaf elongation were related to toxic ion accumulation and depletion of K+ ions in the leaf blades and the accumulation of organic solutes in leaves did not appear to be related to salt tolerance.
Journal ArticleDOI
Contribution of proline and inorganic solutes to osmotic adjustment in cotton under salt stress
TL;DR: In this paper, Physiological responses to salt stress were investigated in two cotton (Gossypium hirsutum L.) cultivars (Pora and Guazuncho) grown hydroponically under various concentrations of NaCl.
Journal ArticleDOI
The effects of salt stress on growth, nitrate reduction and proline and glycinebetaine accumulation in Prosopis alba
TL;DR: In this article, the effects of salinity on some growth and physiological parameters in algarrobo seedlings were investigated, and the results suggest that glycinebetaine enhancement may be important for osmotic adjustment in prosopis alba under salinity stress.
Journal ArticleDOI
Differential responses of superoxide dismutase in freezing resistant Solanum curtilobum and freezing sensitive Solanum tuberosum subjected to oxidative and water stress.
TL;DR: High correlation between SOD activity and the F(v)/F(m )ratio under both PEG induced water stress and MV-mediated oxidative stress was observed, suggesting that SOD can protect PSII from superoxide generated by oxidative and water stress.
