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

Fig. 2

Mg-deficient effects on CO2 assimilation (a), stomatal conductance (gs, b), the ratio of intercellular to ambient CO2 concentration (Ci/Ca; c), transpiration (d), water use efficiency (WUE, e), Fv/Fm (f), DIo/RC (g), DIo/ABS (h), the fraction of OEC in comparison with control (i) and PItot,abs (j) in C. sinensis leaves. Bars represent means ± SE (n = 6 for gas exchange or 8 for fluorescence parameters). Significant differences between Mg-deficient roots and controls were made by unpaired t-test. Four means [two (Mg levels) × two (leaf positions)] were analyzed by two ANOVA followed by Duncan’s new multiple range test. Different letters above the bars indicate a significant difference at P < 0.05
