From: Progressive drought alters architectural and anatomical traits of rice roots
Lateral root branching density basal and apical segments of well-watered (WW) and drought stressed (DS) nodal roots of four rice cultivars. The basal segment consisted of the entire nodal root except for the apical 20 cm segment, which was evaluated separately. a large lateral root branching density and b small lateral root branching density. 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)
