Water use efficiency (WUE), net-photosynthetic rate (Pn), transpiration rate (E) and stomatal conductance (gs) in the leaf tissues of IR29 and Pokkali seedlings grown under 0 mM or 200 mM NaCl treatment for 8 days
| Rice | NaCl (mM) | WUE (%) | Pn (μmol m−2 s−1) | E (mmol m−2 s−1) | gs (mmol H2O m−2 s−1) |
|---|---|---|---|---|---|

| 200 | 0.37c | 0.35c | 1.05a | 2.28c | |
| Pokkali | 0 | 5.63b | 1.35a | 0.25b | 38.45a |
| 200 | 1.11c | 0.75b | 0.71b | 12.26bc |
