| Abstract | Sulla coronaria (L.) Medik is a Mediterranean forage species which has a great agronomic interest. This study investigated the effect of different NaCl concentrations on different physiological parameters. S. coronaria growth was not significantly affected by salt treatment. In addition, it maintained a stable hydric state. However, it decreased at 200 mM NaCl at the root level. Surprisingly, the salt treatment enhanced the photosynthetic activity and the photochemical efficieny of PSII despite of the reduction of the chlorophyll content in this species. The anatomical study showed a succulence of 200 Mm NaCl-treated leaves. Furthermore, the total polyphenols content and the antioxidant capacity increased in both shoots and roots of S. coronaria under salinity, suggesting an efficient antioxidant activity in this species. As a whole, our findings suggest that S. coronaria may be considered as a tolerant glycophyte, and thus may be a good candidate for the rehabilitation of marginal soils. |
