a Relative root length of TX 9425 and Naso Nijo seedlings treated with 0, 0.1, 0.3, 1, 3, 10 mM H2O2 for 3 days. Mean ± SE (n = 20). Asterisks indicate statistically significant differences between two varieties at P < 0.001 (Student’s t test). b Genetic variability in the relative root length in 11 barley varieties treated with 1 mM H2O2 for 3 days. Mean ± SE (n = 20). c Correlation between H2O2–treated relative root length and the overall salinity tolerance (damage index, see Table 1) of 11 barley varieties
