Heat requeriment for inducing budbreaking in different apple cultivars

, 2021
The heat requirements for bud burst of six apple cultivars were evaluated. Shoots with 20 to 25cmlength were submitted to 1,150 cold units. After this treatment, shoots were divided in single bud cuttings and treated at different temperatures (5, 10, 15, 20 and 25oC).
