Abstract

In this lecture I wish to review the basic reasoning and mathematics that lead to the various models of tracer distribution in plants as first put forward by Horwitz (1958). I will then discuss some possible ways of elaborating the Horwitz-type models. I will conclude by showing that at least two Horwitz-type models can be made to fit the tracer profile data reviewed and fitted to error-functions and called diffusion profiles by Canny (1973). Thus, fitting an error-function equation to experimental data is necessary proof, but not sufficient proof, of the Canny-Phillips (1963) bidirectional translocation model.
