Abstract
IN the growing plant, where the photosynthetic tissues make the major contribution to dry-matter production, the absolute growth rate at any time is the product of the rate of increase in weight per unit of leaf (net assimilation rate1, N.A.R.) and the amount of leaf present. The latter is usually expressed in terms of leaf area, which is the product of leaf weight and the area-to-weight ratio.
