图3 外源磷处理对水稻籽粒植酸磷、总磷含量以及植酸磷/总磷的比值的影响(稻穗离体培养)
标以相同小写字母的柱值差异未达到0.05的显著水平。P₀、P₁、P₃、P₆、P₁₂分别代表0、1、3、6和12 mmol L^-1的5个NaH₂PO₄·2H₂O浓度梯度处理。PAP: 植酸磷; Total P: 总磷; PAP/total P: 植酸磷/总磷。

Fig. 3 Effects of different phosphorus levels on grain PAP, total P concentration, and the ratio of PAP to total P (detached panicle culture experiment)
Bars indicated by the same letter among treatments are not significant at the 0.05 probability level. P₀, P₁, P₃, P₆, P₁₂ mean the P (NaH₂PO₄·2H₂O ) levels of 0, 1, 3, 6, and 12 mmol L^-1, respectively. PAP, total P, PAP/total P mean phytic acid-phosphorus, total phosphorus, and phytic acid-phosphorus/total phosphorus, respectively.
