Beam light interception by leaves with undulating edges --A simulation of maize leaf sections. Agric. Meteorol., 19: 399--410.
Formulae allowing the calculation of the shadow projected by, and therefore the extinction coefficient of a leaf surface with undulating edges (idealized maize leaf sections) are presented. The effect of the undulations on light interception is shown to be similar to the effect of an increased erectness at low leaf midrib angle. At high leaf midrib angles, the opposite occurs. The increased erectness is not very sensitive to sun angle and corresponds to a change of leaf angle varying from +27 ° to --18 °, when the leaf midrib angle (to the horizontal) varies from 0 ° to 90 °.
