Temperature Effects on Root Pressure Exudation

JAMES W. O'LEARY

Department of Botany, University of Arizona Tucson, Arizona, U.S.A.

Root-pressure exudation from excised apical root segments of cotton, corn, sunflower, kidney-bean, and castor-bean plants was observed at 25° C and 35° C. The increase in root temperature stimulated exudation from cotton and castor bean, inhibited exudation from sunflower and kidney bean, and seemed not to influence exudation from corn over a 48-hour period. Possible reasons for differences in root pressure exudation among species are discussed, and the support for some of these alternatives given by the data obtained is assessed.
