BBCH-scale
The BBCH-scale is a scale used to identify the phenological development stages of a plant. A series of BBCH-scales have been developed for a range of crop species. Phenological development stages of plants are used in a number of scientific disciplines (crop physiology, phytopathology, entomology and plant breeding) and in the agriculture industry (timing of pesticide application, fertization, agricultural insurance). The BBCH-scale uses a decimal code system, which is divided into principal and secondary growth stages, and is based on the cereal code system (Zadoks scale) developed by Zadoks〔 〕 BBCH officially stands for "Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie". The abbreviation of the scale is also said to unofficially represent the four companies that initially sponsored its development; Bayer, BASF, Ciba-Geigy and Hoechst. 〔(【引用サイトリンク】url=http://www.enotes.com/topic/BBCH-scale )〕 ==See also== BBCH scales for plants or plant groups: *Bean *Beet *Bulb vegetable *Canola, rapeseed *Cereals *Citrus *Coffee *Cotton *Cucurbit *Currants *Faba bean *Grape *Hop *Leafy vegetables forming heads *Leafy vegetables not forming heads *Maize, corn *Musacea *Olive *Other brassica vegetables *Pea *Peanut *Pome fruit *Potato *Rice *Root and stem vegetable *Solaneous fruit *Stone fruit *Strawberry *Sunflower *Weed
