From: Progressive drought alters architectural and anatomical traits of rice roots
Effect of drought stress on large and small lateral root lengths in four rice cultivars. Root lengths are for the apical (deepest) 20 cm nodal root segment. Values shown are means of three replications ± SE. Means with the same letter are not significantly different according to Tukey’s Honest Significant Differences (HSD) test (P ≤ 0.05)
