Model outputs

Output	Equation	Variables
Fraction of incident light intercepted	f _PAR = PAR_c/PAR_i	PAR_i: Incident PAR above the canopy (MJ day⁻¹ m⁻²) PAR_c; PARc intercepted by the canopy (MJ d⁻¹ m⁻²)
Light extinction coefficient	k = –ln(1–f_PAR)/LAI	LAI: leaf area index (m² m⁻²)
Mutual shading	MS = (PAR_isol–PAR_stand)/PAR_isol	PAR_isol: PAR intercepted by the isolated plant (MJ d⁻¹ m⁻²); PARstand: PAR intercepted by the plant in stand (MJ d⁻¹ m⁻²)
Daily carbon assimilation	$A_{d} = \sum_{t = 0}^{24 h} \sum_{l = 0}^{n}$ NRH(PFD_t,l)	PFD_t,l: irradiance of leaflet l at time t (μmol photons m⁻² s⁻¹)
Cumulative light intercepted by the canopy over development	PAR_cumul = PAR_c(50leaves)+…+PAR_c(450leaves)	PAR_c(Σleaves): PAR intercepted by a plant (MJ d⁻¹ plant⁻¹) at a given developmental stage
Cumulative carbon assimilation over plant development	A _cumul = A_{d (50leaves)}+…+A_{d (450leaves)}	A _{d (Σleaves)}: Daily carbon assimilation of a plant (mol CO₂ d⁻¹ plant⁻¹) at a given developmental stage
