AB  - Accurately describing the light response curve of electron transport rate (J-I 
      curve) and allocation of electron flow for ribulose biphosphate (RuBP) 
      carboxylation (J (C)-I curve) and that for oxygenation (J (O)-I curve) is 
      fundamental for modeling of light relations of electron flow at the whole-plant 
      and ecosystem scales. The non-rectangular hyperbolic model (hereafter, NH model) 
      has been widely used to characterize light response of net photosynthesis rate (A 
      (n); A (n)-I curve) and J-I curve. However, NH model has been reported to 
      overestimate the maximum A (n) (A (nmax)) and the maximum J (J (max)), largely 
      due to its asymptotic function. Meanwhile, few efforts have been delivered for 
      describing J (C)-I and J (O)-I curves. The long-standing challenge on describing 
      A (n)-I and J-I curves have been resolved by a recently developed A (n)-I and J-I 
      models (hereafter, Ye model), which adopt a nonasymptotic function. To test 
      whether Ye model can resolve the challenge of NH model in reproducing J-I, J 
      (C)-I and J (O)-I curves over light-limited, light-saturated, and photoinhibitory 
      I levels, we compared the performances of Ye model and NH model against 
      measurements on two C(3) crops (Triticum aestivum L. and Glycine max L.) grown in 
      field. The results showed that NH model significantly overestimated the A (nmax) 
      and J (max) for both species, which can be accurately obtained by Ye model. 
      Furthermore, NH model significantly overestimated the maximum electron flow for 
      carboxylation (J (C-max)) but not the maximum electron flow for oxygenation (J 
      (O-max)) for both species, disclosing the reason underlying the long-standing 
      problem of NH model-overestimation of J (max) and A (nmax).
