Effects of salinity on Na+ exclusion index of A. auriculiformis grown under different levels of salinity at day 150th of salt treatment.
| Salinity levels (dS m-1) | Level of Na+ in 4th phyllode (mg g-1 DW) | Level of Na+ in soil (mg g-1 DW) | Na+ exclusion (%) | Na+ exclusion index |
|---|---|---|---|---|
| 0 | 3.08 ± 0.17d | 11.78 ± 0.11d | 99.74 ± 0.015a | 1 |
| 4 | 4.63 ± 0.14c | 16.28 ± 0.13c | 99.71 ± 0.008ab | 0.91 |
| 8 | 5.25 ± 0.07b | 17.12 ± 0.06b | 99.69 ± 0.005bc | 0.84 |
| 12 | 5.84 ± 0.11a | 17.96 ± 0.04a | 99.67 ± 0.006c | 0.79 |
Values are means ± standard errors of five independent replications (n = 5). Different superscripted letters within the column indicate statistically significant differences among the treatments according to a least significant difference test (P < 0.05). DW, dry weight.
