Different developmental processes are assumed to share a unique response to temperature in crop models. In alfalfa and tall fescue, temperature dependencies differed substantially between processes. Within each species, genotypes from contrasting origins presented identical responses. The differences between temperature dependencies were magnified close to extreme temperatures. This could lead to significant bias of prediction of plant phenology depending on calibration method.
