Summary As in other temperate species, the quince tree (Cydonia oblonga) shows different phenological stages throughout its vegetative growth period in response to changing temperatures. Two cultivars were studied, and 15 phenological stages were identified during their annual cycle, starting at bud dormancy and ending at leaf fall a year later. The different phenological stages were classified according to the BBCH General Scale and Fleckinger's code. The length of all the stages was measured in days and as cumulative day degrees. This study of the quince tree might aid to prevent and deal with any potential physiological and pathological disorders.
