In fruit production, the effects of flowering and fruiting, which modify source-sink relationships, cannot be overlooked and is even more true in tropical fruit production, where the flowering and fruiting phases exceed six months at the individual tree scale. More specifically, little is known about the effects of source/sink balance, and the associated changes in carbon export rate from leaves and leaf carbohydrate concentration, like the ones resulting from the presence of developing fruits, on leaf nitrogen and photosynthetic capacity within the crown of field-growing trees. The amount of carbohydrates supplied to tree fruits depends on the amount produced by leaf photosynthesis, on sink demand and on the availability of the reserve pool. Also, from the point of view of fruit quality, it is essential to understand how pre-harvest factors influence source-sink relationships involved in fruit growth. | Source-sink relationship in litchi verses mango A concept
