Abstract
The coiling of excised pea tendrils in response to mechanical stimulation is accompanied by an increased efflux from their cut bases of electrolytes and label from previously absorbed 14C-acetate and 14C-sucrose. The major excreted cation is H+; H+ loss is potentiated by pretreatment with benzoic acid, which also leaves the tendrils during coiling.
