(1) Water use efficiency also decreased while the rate of transpiration and stomatal conductance remained unchanged.(2) In these studies, stomatal conductance is often measured as the indicator of a leaf response to changing water availability.(3) Skin conductance is measured by applying a constant voltage to the two electrodes.(4) It measures root conductance while water flows opposite to the normal direction.(5) Theoretically, conductivity should not be dependent on the path length of diffusion over which conductance is measured.(6) Radial specific conductance was calculated for each delivery pressure as described above.(7) Then, the measured stomatal conductance was compared with the index.(8) At negative voltages the open channel conductance is higher than at the positive side.(9) At both sites, maximum leaf conductance was related to predawn shoot water potential.(10) These calculations were based on measurements of midday leaf conductance .(11) The authors use those data to produce a new allometric equation relating conductance to body mass.(12) Boundary layer conductance may also be lower with a more open crown, thus further increasing transpiration.(13) The thermal indices were compared with measured stomatal conductance .(14) Hydraulic conductance measurements on single stems at different levels of applied pressure were the repeated factor.(15) The faster subsequent increase in conductance may reflect the faster rate of channel growth.(16) Further, at a given vapour pressure difference, O can serve as a measure of stomatal conductance as well.
