The influence of Gibberellic Acid Treatments on Flowering of Carrots . The influence of GA 3 ‐treatments on flower formation of carrot plants at different light conditions was investigated. No flower formation occurent during natural long day conditions at all GA 3 ‐concentrations (6, 30, 60 ppm). (Fig. 1). Nevertheless under artificial long day conditions flower formation was observed after application of 30 and 60 ppm GA 3 . Apparently a positive interaction between GA 3 ‐application and illumination on shooting exists. Conditions leading to the formation of vegetatives apices from generative are described. (Formation of ‘Hochrosetten’, Fig. 2).
