Relative Elemental Rates and Anisotropy of Growth in Area: a Computer Programme

Abstract

A method of analysis of growth patterns in two dimensions has previously been proposed by Richarads and Kavanagh (1943),which consists of evaluating the divergence of velocity by vector analysis. The method has been adpted for solution by numerical methods, and has been programmed for an electronic computer. The method and the programme are described, and applied to the analysis of leaf growth in Xanthium. These preliminary results suggest that the system could be successfully applied to a wide variety of problem of 2-dimensional growth.
