MODIFYING EFFECTS OF ANCYMIDOL AND GIBBERELLINS ON TEMPERATURE INDUCED ELONGATION IN FUCHSIA X HYBRIDA |
| Author: | H. Tangerås |
| Abstract:
In Fuchsia x hybrida high day/low night temperature resulted in an unfortunate shoot elongation and a delay in flowering. Ancymidol restricted the elongation effectively and promoted the flowering with at least one week. Spraying the plants with gibberellins (GA3 and GA4+7) delayed the flowering with one to two weeks and stimulated shoot elongation. The greatest elongation was observed after use of GA4+7 to plants at low day/high night temperature. This may indicate that the endogenous gibberellin content is low at this temperature combination. | |
