ABSTRACT.
Citrus growth and development is regulated by complex but subtly tuned nutritional and hormonal interaction in response to environmental signalling. Flower induction is stimulated
by low temperatures and water stress and mediated by previous fruit load, being endogenous gibberellins (GAs) content pointed as the main inhibiting hormones. The promoting
role of carbohydrates or nitrogen (N) on fl owering has not been demonstrated, but a minimum content of these compounds seems to be required for fl ower formation. Fruit set is a
critical step for fruit production, being initially regulated by GAs content. Thereafter, during the onset of the source-sink competition, fruit set depends upon carbohydrates and
N availability and fruitlets sink strength. During stage II of fruit development, fruit growth is promoted by auxins, carbohydrates and water accumulation. Afterwards, peel colour
development, which is stimulated by low temperatures, is promoted by the decline of fl avedo?s GAs content and the steady-state level of ethylene, as carbohydrates and abscisic
acid (ABA) increase and N decrease during this fi nal stage.
