已故冈特·克莱因 (Gunter Klein) 提出的假设，即豆叶的自主夜间运动与月球施加的潮汐力有关，已得到检验。利用克莱因博士收集的数据，发现树叶突然向下转动的时间与潮汐力从最小值（“低潮”）或最大值（“高潮”）变化的时间之间存在密切的对应关系。在许多情况下，树叶运动和潮汐力变化的数据集提供了相关行为模式的证据。还提出了连续执行的叶片运动之间的最小 6.2 小时间隔或其倍数的证据。 A Kleinhoonte 早期研究的数据也经过了检查，发现豆叶运动和潮汐力变化之间的对应关系比 Klein 的数据更紧密。因此，克莱因关于叶子和月亮之间相干性的假设得到了支持。
The hypothesis, proposed by the late Gunter Klein, that the autonomous nyctinastic movements of bean leaves are related to the tidal force exerted by the Moon was tested. Using data collected by Dr. Klein, a close correspondence was found between the time at which leaves initiated a sudden downward turning movement and the time at which the tidal force changed from either a minimum ('low tide') or a maximum ('high tide'). In many cases the data sets of leaf movements and the changing tidal force gave evidence of correlative patterns of behavior. Evidence was also adduced for a minimal 6.2-h interval, or multiples thereof, between successively executed leaf movements. Data from an earlier study by A Kleinhoonte were also examined and have been found to show even closer correspondences than do Klein's data between bean leaf-movements and changing tidal forces. Thus, Klein's hypothesis of coherence between leaf and Moon is upheld.
