From: Photosynthetic parameters of a sedge-grass marsh as a big-leaf: effect of plant species composition

Average photosynthesis–irradiance relationship (PN/I) of the theoretical “ecosystem big-leaf” modelled by non-rectangular hyperbolas with real plant species composition. The PN/I relationships are presented separately for different periods: spring, summer and autumn. The PN/I relationship including the whole growing season is shown for comparison with those for individual growth periods. All curves were weighted by the plant species´ partial LAI values in individual growth periods (Fig. 3).
