Book information
Description
BBCH Monograph, 2-nd Edition. — Federal Biological Research Centre for Agriculture and Forestry, 2001. — 158 pp.The extended BBCH-scale is a system for a uniform coding of phenologically similar growth stages of all mono- and dicotyledonous plant species. It results from teamwork between the German Federal Biological Research Centre for Agriculture and Forestry (BBA), the German Federal Office of Plant Varieties (BSA), the German Agrochemical Association (IVA) and the Institute for Vegetables and Ornamentals in Grossbeeren/Erfurt, Germany (IGZ). The decimal code, which is divided into principal and secondary growth stages, is based on the well-known cereal code developed by ZADOKS et al. (1974) in order to avoid major changes from this widely used phenological key.The abbreviation BBCH derives from Biologische Bundesanstalt, Bundessortenamt and CHemical industry.
