# BBCH-scale (other brassica vegetables)

In biology, the BBCH-scale for other brassica vegetables describes the phenological development of vegetables such as brussels sprouts, cauliflower and broccoli using the BBCH-scale.
The phenological growth stages and BBCH-identification keys of other brassica vegetables are:

| 0: Germination | 00 | Dry seed |
| 0: Germination | 01 | Beginning of seed imbibition |
| 0: Germination | 03 | Seed imbibition complete |
