Short photoperiod dormancy development timeline in V. riparia with reference to Seyval's lack of dormancy development under short photoperiods. (A) Overwintering latent buds from short day (SD) treatment show budscale development and periderm development; (B) Actively growing V. riparia shoot tip from long day (LD) vines and V. riparia SD shoot tip during growth cessation (SD14); (C) Decapitated and dormant SD V. riparia (VRS) grapevine, the photograph was taken 28 days after the decapitated SD42 vine was returned to LD-forcing conditions; (D) Individual nodes (3–12 from shoot base, left to right) from V. riparia LD or SD vines (VRL42 or VRS42), the photo was taken 28 days after placing node sections in LD forcing conditions.
