Lines evaluated: control (cv P-73) and progeny of transgenic plant 4 (TG2-4). For each line and treatment, values are given as the means of eight plants ± se. The percentage change in media with NaCl, calculated as [(M/m) − 1] × 100, shown in parentheses, where M and m are the values of the considered parameter in media with and without NaCl, respectively. Means within each column followed by different letters are significantly different according to the LSD test (P ≤ 0.05).
