Assimilate partitioning and distribution in fruit crops: A review

Abstract

Productivity in fruit crops is dependent upon assimilate supply and storage, and on the ability to translocate and partition carbon into reproductive structures in an efficient manner that does not compromise vegetative development to sustain growth during the current season, or in the future. In this article we have reviewed carbohydrate supply and partitioning, source sink manipulation to increase assimilate partitioning towards major sink and have indicated the effect of environmental factors on those processes. The interrelationship between the various sinks at different times during the season is especially important if abiotic or biotic stresses occur. It is only with this understanding that a researcher or producer can make intelligent decisions to optimize economic yield over a sustained period.
