The P-N regression coefficient was moderate in Magnoliales, Coniferopsidae, Pteridophyta, and Asterids, but very high in Caryophyllids, and very low in Rosids. The K-N regression coefficient in trees remained constant regardless of evolution, and that in grasses was high except for Rosids compared with that in trees. The coefficient was very high in Caryophyllids and was very low in Rosids. The N-Ca and N-Mg relationship was not estimated at all, suggesting that the mechanism of Ca and Mg accumulation was completely different from that of N related accumulation. The Zn and Cu concentrations were related to the N concentration. The Al concentration in leaves was negatively correlated with the N, P, K, Ca, Mg, Na, Cu, Zn, Mn, and Fe concentrations, while the N, P, K, and Mn concentrations in leaves increased slightly with the increase of Al concentration in the high Al concentration. The Na concentration in leaves related negatively to the P, Ca, Cu, Zn, Mn and Al concentration range. Thus, it was demonstrated that most of the minerals in leaves accumulate negatively Al and Na indicating that there are antagonistic mechanisms for mineral accumulation in leaves among Al or Na and other mineral elements.
木兰目、松柏纲、蕨类植物和菊类植物中的磷-氮回归系数适中，但石竹目植物中的该系数非常高，蔷薇类植物中的则非常低。树木中的钾-氮回归系数无论进化如何都保持不变，与树木相比，除蔷薇类植物外，禾本科植物中的该系数较高。该系数在石竹目植物中非常高，在蔷薇类植物中非常低。完全没有对氮-钙和氮-镁关系进行估计，这表明钙和镁的积累机制与氮相关积累的机制完全不同。锌和铜的浓度与氮浓度相关。叶片中的铝浓度与氮、磷、钾、钙、镁、钠、铜、锌、锰和铁的浓度呈负相关，而在高铝浓度下，叶片中的氮、磷、钾和锰浓度随着铝浓度的增加而略有增加。叶片中的钠浓度与磷、钙、铜、锌、锰和铝的浓度范围呈负相关。因此，证明了叶片中的大多数矿物质与铝和钠呈负积累，这表明铝或钠与其他矿质元素之间在叶片矿质积累方面存在拮抗机制。
