Abstract

Exposure of a sunflower leaf to hypoxia or chilling stress interrupts translocation from the leaf and also alters the distribution of 14C-assimilates into sugars and amino acids. As translocation from the leaf recovers, there are changes in the distribution of label in the sugars and amino acids that coincide with this recovery. These observations lend support to the idea that certain concentrations of sugars and amino acids are necessary to support translocation out of the leaf.
