Fig. 2. — The relationship between soil water potential and the fraction of total sap flow in vivo from either part of the root system of DI plants (open circles) or the dry part of the root system of PRD plants when soil water potential of the wet pot exceeded (closed triangles) or was less than (closed inverted triangles) –0.01 MPa. Each point represents a single hypocotyl and regression lines were fitted where P < 0.05. (closed triangles) F_dry=0.41 + 0.93Ψ_dry (r²=0.86) and (closed inverted triangles) F_dry=0.91 + 1.65Ψ_dry (r²=0.82).
