Effects of temperature on h uptake and release during circadian rhythmic movements of excised samanea motor organs.
A previous study revealed that Samanea saman leaflets open more completely and close less completely as temperature is increased. We now demonstrate that, as temperature is increased, extensor cells release more H(+) during their swelling phase (opening), but flexor motor cells release less H(+) during their swelling phase (closure).
