Grapevine phenology
Grapevine phenology includes two distinct developmental cycles: vegetative and reproductive (flowering and fruiting). The vegetative cycle takes one growing season to complete. Conversely, the reproductive cycle requires two seasons, with flower inflorescences formed in year one, followed by flower initiation, bloom, and fruiting in year two ...
