The flower formation, i. e., the change of vegetative to generative development is a far-reaching turning-point for the higher plant. Accompanied by basic transformation of metabolism, flower formation leads to development of stamen and carpel, i.e. the fundamental structure for propagation. For plants that die after fructification flower formation therefore means the 'beginning of the end'. The determination of flower formation is a problem highly recognized by plant physiologists: The most important partial process in this physiological development is the transformation of the vegetative point which usually produces foliage leaves. As a consequence of this transformation the primordia are formed (morphogenesis). The change in information is controlled by a flower-hormone which is produced in the leaves and transported to the vegetative point where it activates the so-called 'flowering-genes'. There is no positive information on the chemical structure of flower hormones. Other factors of flower formation control will be discussed.
成花过程，即从营养生长向生殖生长的转变，是高等植物的一个意义深远的转折点。伴随着新陈代谢的根本转变，成花过程导致雄蕊和心皮的发育，即繁殖的基本结构。对于那些在结果后死亡的植物来说，成花过程因此意味着“末日的开始”。成花过程的决定是植物生理学家高度认可的一个问题：在这个生理发育过程中最重要的部分过程是通常产生叶片的营养点的转变。由于这种转变，原基形成（形态发生）。信息的变化由一种在叶片中产生并运输到营养点的花激素控制，在营养点它激活所谓的“开花基因”。关于花激素的化学结构尚无确切信息。将讨论成花过程控制的其他因素。
