S47 note high Cd-accumulative cultivar “Shendao 47”, S315 notes low Cd-accumulative cultivar “Shennong 315”, “A” indicates the first node, “B” indicates panicle node. Gr, grains. P value was tested using the unpaired t test. The different lowercases in the column notes the significant differences (p < 0.05) by the one-way ANOVA test.
