In the qualitative short-day plant Impatiens balsamina, gibberellic acid (GA3) not only promoted the formation of floral buds in response to suboptimal photoinductive conditions and reduced the number of SD cycles that are required for their development into flowers, but also caused initiation of floral buds under non-inductive photoperiods. In plants treated with repeated applications of GA3, the floral buds developed into flowers irrespective of whether the apex was left intact or was removed. In those that received a single application of GA3 the floral buds developed into flowers only in decapitated plants.
在短日植物凤仙花中，赤霉素（GA3）不仅促进了花蕾的形成，以响应次优光诱导条件，并减少了它们发育成花所需的 SD 周期的数量，而且还在非诱导光周期下引发花蕾。在经过重复施用 GA3 处理的植物中，花蕾发育成花，而不管顶端是否完整或被去除。在那些只接受过一次 GA3 处理的植物中，花蕾只有在去顶的植物中才能发育成花。
