Title: THE ROLE OF GIBBERELLIC ACID AND GIBBERELLIN-LIKE SUBSTANCES IN THE DORMANCY OF THE CRANBERRY
Abstract: The role of applied gibberellic acid (GA 3 ) and endogenous gibberellins in the dormancy requirement of the cranberry Vaccinium macrocarpon Ait. cult McFarlin was investigated. Application of GA 3 to unchilled dormant plants resulted in only vegetative growth of the terminal buds. Extraction and bioassay of gibberellin-like substances from both terminal buds and leaves during the 1969–70 season indicate a translocation of these substances from leaves to terminal buds between March 9 and April 6. This coincided with the time of elongation of the terminal buds in the field. The timing of this translocation suggests that these gibberellin-like substances do not play an important role in flower-bud development at this stage.
