Figure 4

The ANOVA and post hoc Tukey test results (depicted as lower-case letters) of the impact of leaf age on (A) absorbance at 530 nm for leaf tissue incubated at 25 °C (Abs25, black bars) and 40 °C (Abs40, grey bars) and (B) relative absorbance (Abs40/Abs25). Note, the leaf age of the first fully expanded leaf (FFEL) is 12 d.
