Description
Hava Delavar and colleagues published a 2026 study asking whether cane measurements and shoot color signal cold-hardiness in grapevines, sparing growers destructive testing. Two cultivars, Prairie Star and Frontenac, were sampled four times across the dormant season, with canes sorted into three thickness classes. The team measured cane dimensions, tracked color values, and gauged freezing tolerance from the heat bud, phloem, and wood tissues released as they froze.
Cane size traits varied without a consistent trend, reflecting sampling time and cane class. Color followed a pattern: shoots grew darker and redder as the season advanced, matching wood maturation. Hardiness rose into mid-dormancy, with wood tissue reaching the deepest tolerance latest, and Prairie Star edging out Frontenac in wood hardiness while bud survival stayed high. Shoot color, especially at the fifth internode, tracked the freezing values. The authors propose color reading as a cheap, non-destructive gauge of acclimation.
