Fig 4. Changes in partitioning of absorbed excitation energy with increasing PPFD.

Fig 4

This was measured at PSI (a, b) and PSII (c, d) level in fronds of Hymenoglossum cruentum and Hymenophyllum dentatum. A dashed line indicates the portion of the curve where comparisons between species were made. These points correspond to the light saturation points of H. cruentum at 24.6 μmol photons m-2 s-1 (IsH.cru) and of H. dentatum at 40.5 μmol photons m-2 s-1 (IsH.den), both obtained from gas exchange measurements. Values are shown as mean ± SE (n = 4).
