This study analyzes the phenological development patterns of promising grapevine rootstocks (Kober 5BB, SO4, and Richter 57) under the typical sierozem soil and sharply continental climate conditions of the Tashkent region. The key phenological phases—including sap flow, bud burst, shoot growth, and leaf fall—were evaluated in relation to the sum of active temperatures (ΣT>0℃ and ΣT>5℃). The results indicate that the duration of the vegetative period and developmental rates are primarily governed by the biological traits of each rootstock; the SO4 rootstock exhibits earlier maturation, whereas Richter 57 is characterized by an extended growing season. These findings provide a scientific foundation for optimizing agrotechnical practices in regional nurseries and selecting climate-resilient rootstocks.
