Phenological stages of the guava tree (Psidium guajava L.)

SummaryAs most fruit tree species, the guava tree (Psidium guajava L.) shows different phenological stages throughout its vegetative period in response to environmental conditions. Sixteen different stages were identified during the annual growing cycle, starting at bud dormancy and ending at fruit ripening. The phenology was coded according to the BBCH General Scale and Fleckinger's code. The duration of every phenological stage was measured in both days and as cumulative degree days.
