Implementation of Photosynthetic Capacity

This section outlines the mathematical formulas used to calculate the electron-limited photosynthetic rate (Wjx) and the Rubisco-limited photosynthetic rate (Wc):

1. Electron-limited photosynthetic rate: Wjx = Kj * Jx
   - Kj is the conversion factor for Jx to Wjx

2. Rubisco-limited photosynthetic rate: Wc = Kc * Vcmax
   - Kc is the conversion factor for Vcmax to Wc
   - Vcmax is the maximum carboxylation capacity

The model assumes that Wc is proportional to Wjx, as described by the equation:
Wc = tα * tc,j0 * Wjx
- tα is a modification factor that adjusts the baseline ratio (tc,j0) of Wc to Wjx, depending on the nitrogen use efficiency for electron transport vs. carboxylation.

This approach, based on the work of Farquhar et al. (1980), Wullschleger (1993), Xu et al. (2012), Maire et al. (2012), and Walker et al. (2014), allows the model to estimate the photosynthetic capacity of the plant under different environmental conditions.
