Parameter levels tested in all combinations stepwise for five cold climate interspecific hybrid grapevine cultivars to minimize root mean square error (RMSE): endodormant temperature threshold (Tth,endo), ecodormant temperature threshold (Tth,eco), endodormant acclimation rate (ka,endo), ecodormant acclimation rate (ka,eco), endodormant deacclimation rate (kd,endo), ecodormant deacclimation rate (kd,eco), theta exponent in deacclimation logistic equation (θ), and ecodormancy boundary (EDB). A total of 2,976,750 combinations were tested per cultivar and for two years (2017 to 2018 and 2018 to 2019).
