Abstract

As an alternative to the Richards Function, a physiologically based mathematical function was developed which assumes that, when light is limiting, CGR is proportional to intercepted radiation and therefore to an exponential function of leaf area. The name 'expolinear' growth equation is proposed. The function is illustrated using sorghum, faba beans and oil palms as examples. Implications for optimum growth strategies are reviewed and caveats are entered
