The BBCH-scale (strawberry) identifies the phenological development stages of strawberry (Fragaria ananassa). It is a plant species specific version of the BBCH-scale.
| Phenological growth stages and BBCH-identification keys of strawberry | |
|---|---|
| Code | Description |
| Principal growth stage 0: Sprouting/Bud development | |
| 00 | Dormancy: Leaves prostrate and partly dead |
| 03 | Main bud swelling |
| Principal growth stage 1: Leaf development | |
| 10 | First leaf emerging |
| 11 | First leaf unfolded |
| 12 | 2nd leaf unfolded |
| 13 | 3rd leaf unfolded1 |
| 1 . | Stages continuous till ... |
| 19 | 9 or more leaves unfolded |
| Principal growth stage 4: Development of stolons and young plants | |
| 41 | Beginning of stolon (runner) formation: stolons visible (about 2 cm long) |
| 42 | First daughter plant visible |
| 43 | Beginning of root development in first daughter plant |
| 45 | First daughter plant with roots (ready for planting) |
| 49 | Several daughter plants with roots (ready for planting) |
| Principal growth stage 5: Inflorescence emergence | |
| 55 | First set flowers at the bottom of the rosette |
| 56 | Inflorescence elongating |
| 57 | First flower buds emerged (still closed) |
| 58 | Early balloon stage: first flowers with petals forming a hollow ball |
| 59 | Most flowers with petals forming a hollow ball |
| Principal growth stage 6: Flowering | |
| 60 | First flowers open (primary or A-flower) |
| 61 | Beginning of flowering: about 10% of flowers open |
| 65 | Full flowering: secondary (B) and tertiary (C) flowers open, first petals falling |
| 67 | Flowers fading: majority of petals fallen |
| Principal growth stage 7: Development of fruit | |
| 71 | Receptacle protruding from sepal whorl |
| 73 | Seeds clearly visible on receptacle tissue |
| Principal growth stage 8: Maturity of fruit | |
| 81 | Beginning of ripening: most fruits white in colour |
| 85 | First fruits have cultivar-specific colour |
| 87 | Main harvest: more fruits coloured |
| 89 | Second harvest: more fruits coloured |
| Principal growth stage 9: Senescence, beginning of dormancy | |
| 91 | Beginning of axillary bud formation |
| 92 | New leaves with smaller lamina and shortened stalk visible |
| 93 | Old leaves dying, young leaves curling; old leaves of cultivarspecific colour |
| 97 | Old leaves dead |
1 Normally after the three leaf stage the bud development occurs in principal growth stage 5. [1]
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.
