Abstract
It has been established that the plant leaves and other above‐ground parts are capable of absorbing chemicals and nutrients. However, there is great paucity of information regarding the mechanisms of ion uptake by leaves and their transport to other parts. Equally not well understood is the phenomenon of retranslocation of elements from one leaf to another during the different stages of plant growth. The results of investigations carried out in this area of foliar uptake and translocation in the last few years are described. In this review, the importance of future studies to investigate the mechanisms involved in foliar transport, the influence of plant growth substances, and the effectiveness of timely supply of specific nutrients during the grain development stage, is stressed.
