In biology, the BBCH-scale for canola describes the
phenological
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation).
Examples include the date of emergence of leav ...
development of
canola plants using the
BBCH-scale The BBCH-scale is used to identify the phenological development stages of plants. BBCH-scales have been developed for a range of crop species where similar growth stages of each plant are given the same code.

The phenological growth stages and BBCH-identification keys of canola are:
1 Stem elongation may occur earlier than stage 19; in this case continue with stage 20
2 Visibly extended internode n develops between leaf n and leaf n+1
