Mass and energy balances of tomato crops 541 Carbon

Basically, the production of biomass by a canopy relies on the net assimilation of atmospheric CO2, that is the balance between gross photosynthesis and respiration. It depends on the amount of available energy light and carbon substrate CO2 , and on the ability of the canopy to intercept light and assimilate CO2. In greenhouses, the assimilation of CO2 is not only important for crop growth, it interacts strongly with the composition of the atmosphere. The daily consump tion of carbon by a...
