N2 - The Brazilian citrus has undergone adaptations due to problems with pests and diseasesaggravated by the large price fluctuation, resulting in the adoption of alternatives, such as higherdensity planting. This transition requires the improvement of practices crop management, such as the adoption of the pruning technique. Its use could be questionable because for a period it can reduce productivity and also retards plant growth due to removal of branches and photosynthetically active leaves, consequently decreasing the total leaf area. Furthermore, thepruning technique also has large interference in source-sink relationship. It’s also importantto list that leaves and stems of citrus trees quantity are sources of carbohydrates, a drasticpruning can cause losses of vegetative growth and fruiting. On the other hand, pruning favorslight penetration and air movement inside the canopy, reducing the plant size and promotesbetter fruits quality. Pruning also helps to control pests and diseases, improving the efficiencyof pesticide application and controlling the alternate bearing in some citrus genotypes. It’simportant to highlight that when the practice of pruning is done periodically, the productivityof crop yield can be maintained, reducing the competition between the canopies. Currently itcan be pointed some types of pruning: training, production (hedging and topping), rejuvenation,cleaning and pruning change of canopy. In general, the best period to prune is after harvestingthe orchard. It’s essential to understand this technique, since an inadequate pruning may be moreharmful that beneficial to the plant.
