Root growth in diploid and tetraploid rice cultivars under salt stress for 5 days. Data represent the mean ± SD (n = 30 × 3 independent biological replicates: all samples were tested in three independent experiments with each included thirty rice plants). Means followed by common letters are not significantly different at P = 0.05 using a protected least-significant difference. Note: (A) Length of the longest root; (B) The number of roots; (C) Fresh weight of the total roots; (D) Dry weight of the total roots.
