Table 1.

Dry weight (DW), relative water content (RWC), and leaf area of Parthenon and Naxos cultivars after different salt treatments for 15 days. Values are means ± standard errors (n = 5). Means followed by different letters are significantly different according to Tukey's test at P < 0.05. The significance of the difference between the two cultivars is given according to the Student's t-test, with ^∗ P < 0.05, ^∗∗ P < 0.01, ^∗∗∗ P < 0.001; n.s: non-significant.
