The effects of sodium chloride and calcium chloride at concentrations of 0.005N and 0.010N upon the respiration of vacuolated and nonvacuolated portions of the root tip of maize have been investigated. In both sections CaCl2 produced marked stimulation, while NaCl had no effect. In this tissue stimulation of respiration does not appear to be directly related to metabolic ion accumulation.
