The objective of this research was to analyze selected minerals in leaves of plants, belonging to 166 species growing in alluvial, low pH, brown forest and serpentine soils. Mineral characteristics of the soils involved were also determined. For the macronutrients, in trees grown in alluvial soil, N, P, Ca, and Mg concentrations of leaves were higher in recently evolved plants than in plants with a longer period of evolution; K concentration remained constant regardless of evolution. In grasses grown in alluvial soil, it was difficult to detect the general tendency of mineral concentration. N, P, and K concentrations in alluvial soil were closely related to those in low pH and serpentine soils. Ca concentration in alluvial soil was lower than that in low pH and serpentine soils. Mg concentration in alluvial soils was higher than that in low pH soils, while lower than that in serpentine soil. Therefore, N, P, and K accumulated according to the plant characteristics for these elements, while Ca and Mg accumulation was strongly affected by the soil properties. For the micronutrients, in trees, Fe and Mn remained constant regardless of evolution; Zn concentration was lower in recently-evolved plants than in plants with a longer period of evolution. In grasses, Fe, Mn, and Zn concentrations in Caryophyllids were high. Except for Caryophyllids, Fe and Cu concentrations remained constant. Mn concentration decreased with evolution, Zn concentration was higher in recently-evolved plants than in plants with a longer period of evolution.
本研究的目的是分析生长在冲积土、低pH值土壤、棕色森林土和蛇纹岩土中的166种植物叶片中的特定矿物质。同时也测定了相关土壤的矿物质特性。对于大量元素，在冲积土中生长的树木中，新近演化的植物叶片中的氮、磷、钙和镁浓度高于演化时间较长的植物；钾浓度无论演化情况如何都保持不变。在冲积土中生长的草类中，很难检测到矿物质浓度的总体趋势。冲积土中的氮、磷和钾浓度与低pH值土壤和蛇纹岩土中的密切相关。冲积土中的钙浓度低于低pH值土壤和蛇纹岩土中的。冲积土中的镁浓度高于低pH值土壤中的，而低于蛇纹岩土中的。因此，氮、磷和钾根据植物对这些元素的特性进行积累，而钙和镁的积累则受到土壤性质的强烈影响。对于微量元素，在树木中，铁和锰无论演化情况如何都保持不变；新近演化的植物中的锌浓度低于演化时间较长的植物。在草类中，石竹科植物中的铁、锰和锌浓度较高。除石竹科植物外，铁和铜浓度保持不变。锰浓度随演化降低，新近演化的植物中的锌浓度高于演化时间较长的植物。
