| Growth stage | Code | Description |
|---|
| 0: Sprouting/Bud development |
00 | Dormancy: leaf and inflorescence buds undifferentiated, closed and covered by green scales |
| 01 | Beginning of bud swelling |
| 03 | End of bud swelling: green scales slightly separated |
| 07 | Beginning of bud burst |
| 09 | Green leaf tips visible |
| 1: Leaf development |
10 | First leaves separating: green scales slightly open, leaves emerging |
| 11 | First leaves visible[1] |
| 15 | More leaves visible, not yet at full size |
| 19 | First leaves fully expanded |
| 3: Shoot development |
31 | Beginning of shoot growth: axes of developing shoots visible |
| 32 | Shoots about 20% of final length |
| 39 | Shoots about 90% of final length |
| 5: Inflorescence emergence |
51 | Inflorescence buds swelling: buds closed, light green scales visible |
| 53 | Bud burst: scales separated, floral tips visible |
| 55 | Flowers visible, still closed (green bud), borne on single or multiflowered leafy or leafless inflorescences |
| 56 | Flower petals elongating; sepals covering half corolla (white bud) |
| 57 | Sepals open: petal tips visible; flowers with white or purplish petals, still closed |
| 59 | Most flowers with petals forming a hollow ball |
| 6: Flowering |
60 | First flowers open |
| 61 | Beginning of flowering: about 10% of flowers open |
| 65 | Full flowering: 50% of flowers open; first petals falling |
| 67 | Flowers fading: majority of petals fallen |
| 69 | End of flowering: all petals fallen |
| 7: Development of fruit |
71 | Fruit set; beginning of ovary growth; beginning of fruitlets abscission |
| 72 | Green fruit surrounded by sepal crown |
| 73 | Some fruits slightly yellow: beginning of physiological fruit drop |
| 74 | Fruits about 40% of final size. Dark green fruit: end of physiological fruit drop |
| 79 | Fruits about 90% of final size |
| 8: Maturity of fruit |
81 | Beginning of fruit colouring (colour-break) |
| 83 | Fruit ripe for picking; fruit has not yet developed variety-specific colour |
| 85 | Advanced ripening; increase in intensity of variety-specific colour |
| 89 | Fruit ripe for consumption; fruit has typical taste and firmness; beginning of senescence and fruit abscission |
| 9: Senescence, beginning of dormancy |
91 | Shoot growth complete; foliage fully green |
| 93 | Beginning of senescence and abscission of old leaves |
| 97 | Winter dormancy period |
