Figure 4.

Callose deposition in rice leaf sheaths in response to Si amendment and BPH infestation. +Si = Si amendment to rice plants at 112 mg Si/kg nutrient solution, –Si = no Si amendment. The histogram bars represent average number of sieve plates with callose deposition observed in the 40 cross‐sections obtained per leaf sheath from 10 different plants per treatment. Error bars represent 1 × SE. An asterisk (*) indicates significant difference between +Si and –Si plants at a certain time post‐BPH infestation at p < .05 via independent samples T test
