Descripción
Chilling and heat requirements for breaking dormancy and flowering were studied in 63 nectarine and118 peach genotypes (Prunus persica (L.) Batsch) for seven years. We compared two methods for estima-tion of requirements and four models for calculation of chill accumulation: Chilling Hours (CH), ChillingUnits (CU), Positive Chilling Units (PCU) and Dynamic, while heat accumulations were estimated in grow-ing degree hours (GDH). Additionally, correlations between chilling requirements, heat requirements andflowering date were established. Our results suggest that the Luedeling model is better than the Alonsomodel to estimate chilling and heat requirements in our field conditions. Moreover, it is recommend-able to calculate the chill accumulation in accordance with the Chilling Hours or Positive Utah models.Additionally, since chilling requirements were positively correlated with flowering dates, they seem tobe important to regulate blooming in nectarine and peach genotypes.
