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

Figure 1

Effects of pH and Al interactions on (a) root, (b) stem, (c) leaf, (d) shoot, (e) whole plant DW, and (f) root DW/shoot DW ratio in C. sinensis seedlings. Bars represent means ± SE (n = 10). 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.
