Increasing Nutrient Solution pH Alleviated Aluminum-Induced Inhibition of Growth and Impairment of Photosynthetic Electron Transport Chain in Citrus sinensis Seedlings

Figure 7

Effects of pH and Al interactions on element uptake (a-l) per plant and (m-x) per root DW in C. sinensis seedlings. Bars represent means ± SE (n = 8 except for 4 for K, Mg, Fe, and Mn). Different letters above the bars indicate a significant difference at P < 0.05. NS, and indicate nonsignificant and significant at 5% and 1% level, respectively.
