Apparent Sap Velocities in Big SagebrushGifford, Gerald F. (Society for Range Management, 1968-07-01)Peak daily sap velocities were rather consistent throughout the year, and were always less than five cm/hr (average of five plants). A 30-variable multiple regression equation involving environmental parameters measured near plants accounted for only 54.05% of variability associated with apparent sap velocity measurements. Big sagebrush plants must, therefore, exert considerable physiological control of transpirational water losses.
