In biology, the BBCH-scale for grapes describes the phenological development of grapes using the BBCH-scale. The phenological growth stages and BBCH-identification keys of grapes are: Growth stage
Bud burst: scales separated light green but sections visible 54: Green or red leaf tips above bud scales 55: First flower buds (compact raceme) visible beside unfolded leaves 56: Beginning of raceme elongation 57: First flower bud separated on elongating raceme 59: Grape stage: all flower buds separated 6: Flowering 60: First flowers open 61
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 Jan Zadoks. [2] The abbreviation BBCH derives from the names of the originally participating stakeholders: "Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie".
