Short episodes of high temperature near flowering can have large negative impacts on grain yields. Observed impacts of heat stress on crop yield is the end result of the integration of many processes. Most crop modellers have only recently recognized the need to improve heat stress responses. Various generic approaches to simulate high temperature impacts on yield are possible. Simulation of canopy temperature can allow to concurrently account for heat and drought stress.
