Abstract
A device for the rapid measurement of leaf areas is described. Leaves are placed between a fluorescent light source, high in the red spectrum, and a photocell covered with an F29 red light filter. The reduction in output of the cell, as measured by a galvanometer, is interpreted in terms of area. The device has been successfully used in a genetic study of leaf size in birdsfoot trefoil.Keywords
