Fig. 2

The chilling accumulation from 1 November to 30 April was calculated using the 12 chilling models. a–l Models C1–C12. Dark blue circles, significant and negative slopes (two-sided F-test, p < 0.01, n = 68 years). Light blue circles, insignificant and negative slopes (two-sided F-test, p > 0.05, n = 68 years). Dark red circles, significant and positive slopes (two-sided F-test, p < 0.05, n = 68 years). Light red circles, insignificant and positive slopes (two-sided F-test, p > 0.05, n = 68 years).
