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).
