Effect of silicon amendment on plant growth and nematode infection. a Nematodes per gram of silicon-amended and non-amended Nipponbare roots were counted at 14 dpi. b Root galls per gram of silicon-amended and non-amended Nipponbare roots were counted at 14 dpi. c The ratio of nematodes in rice roots at different developmental stage is the value of the number of nematodes in different life stage (female or J3/J4) divided by the total number of nematodes in roots. d Roots were stained with acid fuchsin and photographed. Female and J3/J4 were outlined with white lines, respectively. e Plant height at 14 dpi. f Plant weight at 14 dpi. The bars in the different graphs represent the mean ± SE of data from three independent biological replicates, each containing 6 individual plants. Different letters indicate statistically significant differences (Duncan’s multiple range test at P ≤ 0.05)
