图5. 不同氮处理下菌根真菌(AMF)处理对不同基因型水稻氮吸收的平均效应值(平均值±标准误, n = 5)。平均效应值: AMF处理下地上部分¹⁵N浓度变化百分量。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 < 0.01, ***, p < 0.001。

Fig. 5. Effect size of arbuscular mycorrhizal fungi (AMF) treatment on nitrogen uptake in rice with different genotypes under different nitrogen treatments (mean ± SE, n = 5). Effect size: proportion of change of ¹⁵N concentration of rice shoots by AMF treatment. 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, there was no significant difference. ns, not significant; **, p < 0.01; ***, p < 0.001.
