The BBCH-scale (grape) identifies the phenological development stages of grapes (Vitis vinifera ssp. vinifera). It is a plant species specific version of the BBCH-scale.
A downloadable version [1] of the BBCH Scales, including illustrations, is available from the BBA [2] (Federal Biological Research Centre for Agriculture and Forestry)
| Phenological growth stages and BBCH-identification keys of grape | |
|---|---|
| Code | Description |
| Principal growth stage 0: Sprouting/Bud development | |
| 00 | Dormancy: winter buds pointed to rounded, light or dark brown according to cultivar; bud scales more or less closed according to cultivar |
| 01 | Beginning of bud swelling: buds begin to expand inside the bud scales |
| 03 | End of bud swelling: buds swollen, but not green |
| 05 | “Wool stage”: brown wool clearly visible |
| 07 | Beginning of bud burst: green shoot tips just visible |
| 08 | Bud burst: green shoot tips clearly visible |
| Principal growth stage 1: Leaf development | |
| 11 | First leaf unfolded and spread away from shoot |
| 12 | 2nd leaves unfolded |
| 13 | 3rd leaves unfolded |
| 1 . | Stages continuous till . . . |
| 19 | 9 or more leaves unfolded |
| Principal growth stage 5: Inflorescence emerge | |
| 53 | Inflorescences clearly visible |
| 55 | Inflorescences swelling, flowers closely pressed together |
| 57 | Inflorescences fully developed; flowers separating |
| Principal growth stage 6: Flowering | |
| 60 | First flowerhoods detached from the receptacle |
| 61 | Beginning of flowering: 10% of flowerhoods fallen |
| 62 | 20% of flowerhoods fallen |
| 63 | Early flowering: 30% of flowerhoods fallen |
| 64 | 40% of flowerhoods fallen |
| 65 | Full flowering: 50% of flowerhoods fallen |
| 66 | 60% of flowerhoods fallen |
| 67 | 70% of flowerhoods fallen |
| 68 | 80% of flowerhoods fallen |
| 69 | End of flowering |
| Principal growth stage 7: Development of fruits | |
| 71 | Fruit set: young fruits begin to swell, remains of flowers lost |
| 73 | Berries groat-sized, bunches begin to hang |
| 75 | Berries pea-sized, bunches hang |
| 77 | Berries beginning to touch |
| 79 | Majority of berries touching |
| Principal growth stage 8: Ripening of berries | |
| 81 | Beginning of ripening: berries begin to develop variety-specific colour |
| 83 | Berries developing colour |
| 85 | Softening of berries |
| 89 | Berries ripe for harvest |
| Principal growth stage 9: Senescence | |
| 91 | After harvest; end of wood maturation |
| 92 | Beginning of leaf discolouration |
| 93 | Beginning of leaf-fall |
| 95 | 50% of leaves fallen |
| 97 | End of leaf-fall |
| 99 | Harvested product |
