Abstract
Differences in heat requirements for blooming and leafing were investigated in peach [Prunus persica (L.) Batsch] using artificially chilled excised s hoots and potted trees. 'Della Nona' and 'BR-1' have high heat requirements ; 'Planalto', 'Sunlite', and 'Eldorado' are intermediate; and 'Precocinho' and 'Riograndense' have low heat requirements. Prolonged chilling enhanced leafing more than blooming. Flower and vegetative buds have different heat requirements during ecodormancy.
