日照长度对植物的许多发育功能有着深远的影响。克莱布斯在1918年首次认识到环境中存在这种极其微妙的因素。日照长度作为植物发育的一个因素，其生物影响程度是由Garner和Allard在1920年首次证明的。他们引入了“光周期”一词来描述植物对日长的发育反应。从那时起，许多工作者帮助阐明了控制光周期反应的原理，但其潜在的机制或生理动力学尚未被发现。最近出版的三本著作（Whyte, 1946; Murneek et al., 1948; Wigglesworth et al., 1948）广泛地回顾了有关植物光周期现象的生物学文献。因此，目前没有必要进行详细的审查。然而，由于最近几年发表的研究已经大大改变了对光周期现象的理解，因此人们相信，对该领域现状的简要回顾可能是有益的。为了简单起见，本文的讨论将仅限于花起始的光周期控制，除非有关其他光周期现象的特定兴趣点被认为值得注意。对花形成的研究一直在寻找发生巨大变化的原因，这种变化发生在营养植物的分生组织，
LE ENGTH of day has a profound effect on many developmental functions of plants. The existence of this extremely subtle factor in the environment was first recognized by Klebs in 1918. The extent of biological impact of day length as a factor in plant development was first demonstrated by Garner and Allard in 1920. They introduced the term photoperiodism to cover the developmental responses of plants to day-length. Since then, many workers have helped to clarify the principles governing the photoperiod responses, but the underlying mechanism or physiological dynamics are yet to be discovered.The biological literature dealing with photoperiodism in plants has been extensively reviewed in three recent books (Whyte, 1946; Murneek et al., 1948; Wigglesworth et al., 1948). Consequently there is no need for a detailed review at this time. However, because researches published even in the last few years have considerably altered the understanding of photoperiod phenomena, it is believed that a brief review of the present status of the field may be constructive. For the sake of simplicity, the discussion in this review will be limited to the photoperiodic control of flower initiation, except where specific points of interest concerning the other photoperiodic phenomena are considered noteworthy. The study of flower initiation has been a search for the cause of the dramatic change which takes place when the meristem of a vegetative plant,
