FIGURE 2.

Mass gain of the third instars rice leaffolder (LF) fed on Si amended (+Si) and un-amended rice plants of Si transporter deficient mutant OsLsi1 and the corresponding wild type (WT). Different genotypes of rice plants were fertilized with 0 or 1.4 mM silicon (Si) amendment for 30 days, and then treated by third-instar LF larvae that had been weighed and starved for 2 h. All larvae were weighed after 3 days of infestation, and the means of mass gain were then calculated. Values are mean ± SE (n = 20). Letters above bars indicate significant differences among treatments (Tukey’s multiple range test, P < 0.05).
