During the processes of growth and development of climbing Phaseolus vulgaris L. shoots, 3 parameters or variables of movement consisting of a horizontal component, a vertical component, and speed display ultradian rhythms. Generally, they have periods in the range of 80 to 110 min. Shoot elongation is reflected in the chronograms of the vertical component by an increasing trend in the pattern of the oscillations. Characteristics of the rhythmic movements of the shoot, such as circulating phase differences among cells, may provide a useful tool in exploring interactions between temporal and structural components of biological organization, synchronization, and communication.
