From: Lanthanum nitrate enhances aroma precursors of tobacco leaves via influencing chemical components and photosynthetic characteristics

Fig. 4

The plastid pigments of tobacco leaves under different lanthanum nitrate concentrations treatments (A) and the changes compared to control (B). The error bars in subgraph A represent standard error of 3 individual plants (n = 3). Different lowercase letters above the bars indicate significant differences between treatments (LSD, P < 0.05). In subgraph B, vertical lines indicate the confidence intervals of the effect size between the treatments and the control.
