图3. 不同氮处理对不同根形态基因型水稻地上部分¹⁵N浓度的影响(平均值±标准误, n = 5)。arl1, 不定根缺失突变体水稻; iaa11, 侧根缺陷型突变体水稻; Kas, 野生型水稻; rhl1, 根毛缺陷型突变体水稻。柱形图上方不同小写字母表示处理间差异显著( p < 0.05)。neu, 氮处理效应; st, 基因型效应; neu × st, 氮处理与基因型交互效应。ns, 没有显著差异; *, p < 0.05; ***, p < 0.001。

Fig. 3. Effect of different nitrogen treatments on ¹⁵N concentrations of rice shoots with different genotypes (mean ± SE, n = 10). arl1, adventitious rootless mutant; iaa11, lateral rootless mutant; Kas, wild type; rhl1, root hairless mutant. Different lowercase letters above the columns represent significant differences between treatments according to least significant difference test (p < 0.05). neu, nitrogen treatment effect; st, genotype effect; neu × st, interaction effect between nitrogen treatment and genotype. ns, not significant; *, p < 0.05; ***, p < 0.001.
