début du texte] namely light and CO2, into biomass. This occurs during a given period of time, the duration of which depends essentially on the air temperature and on the precocity of the genotype in question. During the same period of time, the plant requires an amount of water which depends on environmental conditions (light, air humidity, wind) and on plant variables such as stomatal conductance and leaf area. It follows that the biomass accumulated by a plant primarily depends on environmental conditions, but also depends on plants traits with genetic variability. The objective of this chapter is to provide a basis for analysing yield from a knowledge of environmental conditions, thereby enabling characterisation of the differences in behaviour between genotypes.
