Patterns of assimilate transport from leaves to fruit within a kiwifruit (Actinidia deliciosa) lateral

SummaryKiwifruit leaves began to export 14C-assimilate when they were 49 to 64% fully expanded. The translocation was bidirectional, but within an intact lateral, assimilates flowed along pathways which linked the fruit on the nth node with its subtending leaf and, at least, with the leaves at nodes n+5 and n+8. However, after the lateral was pruned, the pattern of translocation was altered, so that all the distal leaves supplied each fruit.
