TF_root-stem = Cd_stem/Cd_root; TF_stem-leaf = Cd_leaf/Cd_stem; TF_stem-panicle = Cd_panicle/Cd_stem; TF_leaf-panicle = Cd_panicle/Cd_leaf; TF_{panicle-glume} = Cd_glume/Cd_panicle; TF_{panicle-grain} = Cd_grain/Cd_panicle. Values are means (n = 3). The * indicated that there were significant differences among treatments of the same rice variety (P < 0.05).
