Table 1 Pearson correlation coefficient matrix for 11 physiological parameters in C. sinensis leaves. Data are from Figs. 2 and 3; *, ** and *** indicate a significant difference at P < 0.05, P < 0.01 and P < 0.001, respectively. A: CO2 assimilation; FOEC: The fraction of OEC in comparison with control; EL: Electrolyte leakage; SAP: Superoxide anion production rate; HP: H2O2 production rate

From: Responses of reactive oxygen species and methylglyoxal metabolisms to magnesium-deficiency differ greatly among the roots, upper and lower leaves of Citrus sinensis
