title: H Fluxes in Excised Samanea Motor Tissue : II. Rhythmic Properties.
abstract: Homogeneous groups of cells were excised at regular intervals from opposing (extensor and flexor) motor tissue of Samanea saman (Jacq) Merrill maintained in white light for 34 hours. H(+) fluxes between the tissue and bathing solution were then monitored during 30 minutes of darkness. Flux rates in both cell types vary with circadian rhythms. Flexor cells secrete H(+) to the medium during two-thirds of the circadian cycle and take up H(+) during the remainder of the cycle, while extensor cells take up H(+) from the medium during the entire cycle.
