Leaf Photosynthesis
The relation between available radiation and
CO2 gross assimilation by a single leaf is
described by an asymptotic exponential relation
FG = AMAX * ( 1 − EXP(− EFF*PAR/AMAX) )
FG: assimilation in kg(CO2)ha-1(leaf)h-1
PAR: photosynthetically active radiation(J m-2s-1)
EFF: is the light use efficiency in
kg ha-1h-1/J m-2s-1
AMAX: maximum rate of CO2 assimilation in
kg(CO2)ha-1(leaf)h-1.

Respiration
Maintenance respiration (MRR): Energy consumed to meet maintenance requirements.
MRRorg=Rorg*Sorg
Growth respiration (EC): Respiration providing energy for the conversion of primary photosynthesis into structural plant materials like, proteins, cellulose, fats, lignin.
