Abstract

An internationally acceptable scale for recording the growth stages of cereals is clearly desirable. Such a scale should be accept3 ble to agronomists, plant breeders, plant pathologists, plant physiologists, taxonomists and all others concerned with recording details of crop growth. The decimal code developed by Zadoks, Chang and Konzak has been widely recognized as the best scale available. It was con- sidered in detail by a committee comprising experts in the disciplmes concerned, who made a number of proposals which have been incorporated in the scheme which has been published in mimeographed form by Eucarpia (The European Association for Research in Plant Bre~ding) a!1d is now published here. It is also hoped that it will be published in America in the Wheat, Oat and Barley Ne\\'sletters. Users of the code should appreciate that it refers throughout to individual pbnts, or, where appro- priate, to the main shoois ofsllch plants, and that the growth stages described are not mutualiy exclusive. A plant may, for example, be ,equally well described in terms of the number of leaves unfolded on its main shoot or in terms of stem elongation. At the same time the number of tillers developed is more Jikely to be descriptive of plant spacing or agronomic treatment than of developmental stage.
