A Computer Program for Deriving Growth-Functions in Plant Growth-Analysis

Abstract

In many plant growth studies it is often useful to compare values of the several well-known growth-functions between species or treatments or at different times during an experiment. For over 50 years it has been customary to derive such functions in the form of mean values over the intervening period of time between two harvests (see Radford (1967) for a review of conventional formulae). More recently, however, various workers have taken advantage of high-speed computing facilities to fit smooth curves to experimental data and thence to derive fitted values for the growth-functions which may be plotted continuously.
