Semi-circadian rhythms of spontaneous photon emission from wheat seedlings germinated and grown in a constant environment (darkened chamber) were found to be synchronized with the rhythm of the local gravimetric (lunisolar) tidal acceleration. Time courses of the photon-count curves were also found to match the growth velocity profile of the seedlings. Pair-wise analyses of the data--growth, photon count, and tidal--by local tracking correlation always revealed significant coefficients (P > 0.7) for more than 80% of any of the time periods considered. Using fast Fourier transform, the photon-count data revealed periodic components similar to those of the gravimetric tide. Time courses of biophoton emissions would appear to be an additional, useful, and innovative tool in both chronobiological and biophysical studies.
在恒定环境（暗室）中发芽和生长的小麦幼苗自发光子发射的半昼夜节律被发现与当地重力（日月）潮汐加速度的节律同步。还发现光子计数曲线的时间进程与幼苗的生长速度曲线相匹配。通过局部跟踪相关性对数据（生长、光子计数和潮汐）进行成对分析，在所考虑的任何时间段中，超过80% 的分析结果总是显示出显著系数（P > 0.7）。使用快速傅里叶变换，光子计数数据显示出与重力潮汐相似的周期性成分。生物光子发射的时间进程似乎是生物钟学和生物物理学研究中一种额外的、有用的和创新的工具。
