Sensitivity to Temperature of Epidemiological Processes at Leaf Scale, a Preliminary Step Towards FSPMs of Sick Wheat

Function-Structure Plant models (FSPM) seem attractive to better understand the complex interactions between plant growth, canopy morphogenesis, and epidemics. Epidemics are driven by climate factors and among them, temperature is known to play a major role. Thus, weather station measurement is commonly used to drive epidemics models. However, the relationship between climate and within-canopy microclimate is mainly affected by the canopy architecture. Thus, the general question addressed in this study is: where air temperature should be measured as input of FSPM for sick plants?
