Chilling units and chilling hours for southern region of Brazil and Aomori in Japan
Revista Eletrônica Científica da UERGS, 2018 The brazilian apple production are located in the southern region, with the best areas in altitudes ranging from 800 to 1400 m, with great variability in the number of Chilling Hours (CH) and Chilling Units (CU) in the different regions and years. The objective of this study was to compare CH equal or below 7.2°C and CU by the North Carolina Modified ...
