Mineral characteristics of the leaves of 166 plant species with different phylogeny in the temperate region

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.
