Fig. 1 Light-response curves of electron transport rate (ETR- I) for Coreopsis lanceolata (A), Vitex negundo (B) and Bidens frondosa (C) (mean ± SE). Equation (2) is ETR =α (1-β I) / (1 + γI) I. Here α is the initial slope of ETR-I, β is the photoinhibition term, γ is the saturation term, I is light intensity; Equation (9) is ETR =α'β'IΦPSIImaxe-kwI. Here α' is the light absorption coefficient of leaf, β' is the light energy distribution coefficient between photosystem II and photosystem I, ΦPSIImax is the maximum photochemical quantum efficiency while I = 0, kw is a constant; Equation (11) is ETR = α'β'(Fv/Fm) PARsat [1-exp(-I/PARsat)]. Here Fv/Fm is the maximum quantum of photosystem II, PARsat is the saturation irradiance.
