  "abstract": "<p>Salt-alkali stress is a major environmental factor that seriously limits crops development and productivity worldwide. The objective of this study is to compare growth and physiological responses of sainfoin (<em>Onobrychis viciaefolia</em>) to alkali (NaHCO<sub>3</sub>) and salt-alkali (NaCl: NaHCO<sub>3</sub>) stress, by investigating biomass, photosynthetic pigments, antioxidant enzymes, inorganic ions, organic substances such as proline and sugars. It was shown that both alkaline and saline-alkaline stress treatments significantly reduced fresh weight (FW) and dry weight (DW), chlorophyll (Chl) contents, K<sup>+</sup>&nbsp;concentrations, antioxidant enzymes activity and soluble sugars contents, whereas clearly increased malondialdehyde (MDA), proline and Na<sup>+</sup>&nbsp;concentrations in sainfoin plants compared with control (no added NaCl and NaHCO<sub>3</sub>). It is also observed that in the 150 mM NaHCO<sub>3</sub>, peroxidase (POD) activity, soluble sugar contents and K<sup>+</sup>/Na<sup>+</sup>&nbsp;ratio in plants under NaHCO<sub>3</sub>&nbsp;treatment were lower than those in plants under NaCl: NaHCO<sub>3&nbsp;</sub>treatment. These results suggested that the damages caused by alkaline stress on the growth of sainfoin plants are more serious than those caused by saline-alkaline stress treatments. The findings of the present work provide a basis for understanding the physiological responses to saline-alkaline stress in forage legumes.</p>",
