Applied clusters of phenology models. Models starting accumulation of forcing units (FU) at a specific day of year (DOY) are forcing (F) or photoperiod incorporating forcing (F.PP) models. Models starting FU accumulation after reaching a threshold for chilling units (CU) are chilling-and-forcing (CF) or chilling-and-forcing and photoperiod incorporating (CF.PP) models
