Der Einfluß von Gibberellinsäurespritzungen auf das Blühverhalten von Karotten

摘要

The influence of Gibberellic Acid Treatments on Flowering of Carrots.The influence of GA3‐treatments on flower formation of carrot plants at different light conditions was investigated. No flower formation occurent during natural long day conditions at all GA3‐concentrations (6, 30, 60 ppm). (Fig. 1). Nevertheless under artificial long day conditions flower formation was observed after application of 30 and 60 ppm GA3. Apparently a positive interaction between GA3‐application and illumination on shooting exists. Conditions leading to the formation of vegetatives apices from generative are described.
