Abstract

GROWTH STAGES IN CEREALS ILLUSTRATION OF THE FEEKES SCALE by E. C. LARGE Plant Pathology Laboratory, Harpenden The following scale, essentially that originally provided for wheat by Feekes (1941) but with some additional notes by the late Dr. F. Earnshaw of the National Institute of Agricultural Botany, and with my illustrations from plants in the field, has been used extensively in advisory and investigational work on cereals in England and Wales during the past four years. With variations (as noted) in the heading stages, the scale has been found applicable not only to wheat, but also to oats, barley and rye. It is in use for defining the course of growth of cereal crops in relation to seasonal conditions and variety ; for indicating the stage of development of the plants when mildew, rust and other disease and pest assessments are made ; and also in connection with work on growth-regulator weed-killers, where the risk of damage to cereals is crucially dependent on the stage of growth at which the material is applied.
