ABSTRACT:
Chilling requirement is a characteristic that limits temperate fruit crops cultivation under a subtropical climate. Several mathematic models have been developed, differing on the relative value of chilling units, in order to estimate the chilling accumulation on a given site. The present work compared eight of these models using data from hourly temperatures from May to August, from a period of 11 years, collected in Pelotas, RS, Brazil, aiming to characterize the region regarding the chilling accumulation for the cultivation of deciduous fruit trees and to check if a model using average temperatures is suitable enough to be used when hourly temperatures were not available. The eight tested models were: Chilling Hours (?7.2°C); Chilling Hours (?11°C); Utah; Low Chill; Dynamic; Mean Temperatures; Positive Utah and Taiwan. The results showed large differences between years, regardless of the model used. However, the Taiwan and Low Chill models seemed more suitable for the estimation of the accumulation of cold in the Pelotas region. The Medium Temperatures model can be used as a valid option since it has a high correlation with the other models and easy data availability.

El aumento en la concentración de gases de efecto invernadero tiene como resultado cambios en la variabilidad climática diaria, estacional, interanual y a lo largo de decenios. y son de esperar cambios en la frecuencia, intensidad y duración de fenómenos climáticos extremos (IPCC, 2013; IPCC, 2014). La variabilidad climática y la ocurrencia de eventos extremos (heladas, granizos, sequías) resulta en perjuicios muy importantes para el sector agropecuario y frecuentemente el sector requiere de varios años para recuperarse económica y financieramente de los daños ocasionados (web INIA-GRAS). Teniendo esto en cuenta, la variabilidad climática en Uruguay es un factor muy relevante y el análisis y caracterización de la misma a nivel nacional resulta de fundamental importancia para la gestión de riesgos asociados al clima en la producción agropecuaria y otros sectores de la economía del país. |
