Figure 2.

Deepoxidation of V in detached avocado leaves during chlorophyll fluorescence assay of photosynthetic parameters. Pigment composition of mature shade leaves is shown before and after photosynthetic induction assay at 300 μmol photons m⁻² s⁻¹ for 6 min (A) and RLRC assay from 0 to 410 μmol photons m⁻² s⁻¹ (B). Note that values for L* have been reduced by 100 mmol mol⁻¹ chlorophyll to facilitate stoichiometric presentation of the data, as in Figure 1 (i.e. the scale for L* corresponds to 100–160 mmol mol⁻¹ chlorophyll). Values shown are means ± se (n = 4).
