| Treatment | Leaf length (cm) | No. of leaves | Leaf thickness (mm) | Leaf thickness (mm) | Leaf succulence (mg f. wt mm−2) | Leaf length (cm) | No. of leaves | Leaf thickness (mm) |
| Control | 9·7 ± 0·3a | 4·0 ± 0·1a | 0·70 ± 0·02a | 0·67 ± 0·02a | 0·85 ± 0·02a | 11·7 ± 0·3a | 4·8 ± 0·1a | 0·69 ± 0·02a |
| Salt spray | 9·3 ± 0·3a | 3·9 ± 0·2a | 0·78 ± 0·02b | 0·79 ± 0·02b | 0·99 ± 0·02b | 12·4 ± 0·4a | 4·8 ± 0·1a | 0·77 ± 0·02b |
Plants were grown on potting soil. Measurements were performed on the same plants in weeks 8 and 13 with 19 and 45 d of salt spray, respectively. Leaf thickness was measured with a thickness gauge and expressed in millimetres.
Values are means ± s.e. (n = 30). Means in the same column that have the same letter are not significantly different at P < 0·05 (one-way ANOVA).
