The effect of gibberellin A3(GA3) treatments on flowering of seed-grown globe artichoke (Cynara scolymus)was investigated under controlled environment and field conditions. GA3induced flower initiation in lines #x2018;060#x2019; and #x2018;Talpiot#x2019; under strictly noninductive, short-day-high-temperature conditions. In #x2018;Talpiot#x2019;, GA3induced microscopically detectable flower initiation but no stem elongation, suggesting involvement of gibberellins in the flower formation process. Under field conditions, GA3replaced the cold requirements of line #x2018;HU 271#x2019;, thereby enabling the start of flowering during autumn. The vegetative clone Bianca d'Espana flowered during autumn without GA3treatment, probably due to its minimum cold requirements. Definition of the response type and the role of gibberellins in the flowering of globe artichoke are discussed.
