 Vascular connections exist between sources and sinks and those that are the most direct have been shown to receive more photosynthates than those that must travel through extensive connections.This also goes for proximity those closer to the source are easier to translocate sugars to.Developmental stage plays a large role in partitioning, organs that are young such as meristems and new leaves have a higher demand, as well as those that are entering reproductive maturity—creating fruits, flowers, and seeds.
