Abstract
Floral and vegetative buds of ‘Tifblue’ and ‘Woodard’ rabbiteye blueberries (Vaccinium ashei Reade) in various stages of development were exposed to cold under controlled conditions. The temperature required to damage a floral bud was inversely related to the stage of the bud; closed floral buds survived −15°C, but open buds were killed by −1°. Floral buds exposed to but undamaged by cold developed as rapidly as buds with no exposure to cold. Cold hardiness of vegetative buds was similar to that of floral buds.Keywords
