A quantitative understanding of the phases of sensitivity to photo-thermal environment is important if the accuracy of flowering models is to be improved and if the timing of long and short day treatments in protected cropping is to be optimized. A simple method of quantifying the duration of the phases of sensitivity to photoperiod is through the use of reciprocal transfer experiments where plants are transferred between long and short days at regular intervals throughout development. The advantages and disadvantages of different analytical approaches used to analyse such data sets are examined. Inconsistencies between the approaches are highlighted, as are differences in the way authors have interpreted data. The problem of confounding the effects of photoperiod and light integral is considered, as is the need to separate the number of inductive cycles needed for flower commitment from the length of the juvenile phase. The effects of photo-thermal environment on the duration of these phases of photoperiod sensitivity are discussed, together with topics requiring further development.
如果要提高开花模型的准确性以及优化设施栽培中长日照和短日照处理的时间，那么对光热环境敏感性阶段进行定量理解就很重要。一种量化光周期敏感性阶段持续时间的简单方法是通过使用相互转移实验，即植物在整个发育过程中定期在长日照和短日照之间转移。研究了用于分析此类数据集的不同分析方法的优缺点。强调了不同方法之间的不一致性，以及作者解释数据方式的差异。考虑了混淆光周期和光积分效应的问题，以及将花诱导所需的诱导周期数与幼年期长度区分开来的必要性。讨论了光热环境对这些光周期敏感性阶段持续时间的影响，以及需要进一步研究的主题。
