a
Ph, Phloem; Xy, xylem.
b
Values (means ± sd) followed by the same letter within a column are not significantly different; Scheffe's post-hoc pairwise comparison (P < 0.05).
c
Kruskal-Wallis one-way ANOVA by ranks. Rice variety B5 carries both BPH resistance genes Bph14 and Bph15; RI35 and YHY15 carry genes Bph14 and Bph15, respectively; TN1 has no BPH resistance gene.
