Budbreak of pecan cultivars subject to artificial chill

ABSTRACT Chill is a limiting factor in commercial production of temperate fruit due to their dormancy mechanism. Thus, knowledge of chill requirements of cultivars is important to reach successful production. This study aimed at evaluating responses given by different pecan cultivars subject to artificial chill. Pecan branches were collected from twelve 9-year-old cultivars – Success, Shoshoni, Farley, Elliott, Mohawk, Jackson, Desirable, Barton, Importada, Shawnee, Choctaw and Melhorada – in two orchards located in Canguçu, Rio Grande do Sul (RS) state, Brazil, in 2017 and 2018.
