Title: Late Blooming in Apple
Author: J.M. Thompson
At Blairsville, Georgia, in the Appalachian Mountains (el. 20001), a sampling of approximately 500 cultivars of Malus syloestris, Mill. showed bloom date variability of at least a month. The earliest, 'Caroline Hopkins', bloomed 7 days before the standard variety, 'Red Delicious'; whereas the latest, 'Spatbluhender', bloomed 24 days after the standard. Preliminary evidence from an Upper Coastal Plain location, Byron, Georgia ( el. 650'), indicates even greater disparities in all years with the greatest spreads being associated with the interaction of warm winters with cultivars having a high chilling requirement. Inheritance data are being gathered, but all results must be considered to be tentative.
