FIGURE 2.
Percentage out of 30 seedlings of S. hermonthica at stage (A) I, failure to attach to the root due to a lack of haustorium formation (Figure 1a); (B) II, successful attachment but no shoot elongation (Figures 1b–d); (C) III, shoot necrosis after reaching the four or more leaf pairs stage (Figures 1e,f); and (D) IV, successful parasitism with healthy shoots (Figures 1g,h) on the roots of 27 rice varieties in the first rhizotron experiment at 21 DAI. Means followed by a common letter are not significantly different by Tukey’s HSD test in each growth stage (p < 0.05).
