FIGURE 2.
Changes in Fm (A,C) and Pm (B,D) in Psychotria rubra and Pometia tomentosa during treatments at 25°C associated with high light intensities of 1000 (A,B) and 2000 (C,D) μmol photons m–2 s–1. The means ± SE were calculated from six independent plants. Asterisks indicate significant differences between Psychotria rubra and Pometia tomentosa.
