When plants of Silene coeli-rosa (L.) Godron were induced by seven long days, then exposed to darkness for 48 h before being returned to short days, they went on to initiate flowers with a delay of about 2 d. The synchronisation of cell division which normally occurs before flower initiation was suppressed, showing that it is not essential for flowering. Periods of darkness of up to 240 h inhibited apical growth and leaf initiation but did not prevent eventual flowering in short days. The commitment of the apex to flower was therefore maintained while apical growth was inhibited.
当石竹科的石竹（Silene coeli-rosa（L.）Godron）植物经过七天的诱导，然后在返回短日照之前被黑暗处理 48 小时，它们会延迟大约 2 天开始开花。通常在花起始前发生的细胞分裂的同步化被抑制，表明其对于开花不是必需的。长达 240 小时的黑暗期抑制了顶端生长和叶片起始，但并没有阻止最终在短日照下开花。因此，在顶端生长受到抑制的同时，顶端向花的发育方向被确定。
