Photosynthesis limitations in cacao leaves under different agroforestry systems in the Colombian Amazon (original) (raw)
Fig 3
Leaf photosynthesis-CO2 response curves of cacao as modelled using the FvCB model.
A is the net carbon assimilation rate, _C_i is the intercellular CO2 concentration. Symbols represent the measured values, and the black line represents the fitted FvCB model of photosynthesis. Colored lines indicate the two photosynthesis rates in the FvCB model. _A_c and _A_j are the gross photosynthesis rates when RuBisCO activity and RuBP regeneration are limiting, respectively. a. cacaotal with Musaceae plantation and high mean daily PAR incident radiation (700 μmol m-2 s-1; H PAR), b. low diversity of clustered vegetation and medium mean daily PAR (400 μmol m-2 s-1; M PAR), c. diversified multistrata vegetation and low mean daily PAR (300 μmol m-2 s-1; L PAR).
