El-Sharkawy, Mabrouk A.Cock, James H.[The humidity factor in stomatal control and its effect on crop productivity]The humidity factor in stomatal control and its effect on crop productivity

Analysis of previously published data shows that an extremely close correlation (r(2) = 0.83) exists between stomatal sensitivity to changes in leaf to air vapor pressure deficit and the maximum leaf conductance at low VPD in a wide range of plant species. The hypothesis is presented that stomata...


El-Sharkawy, Mabrouk A.Cock, James H.[Stomatal sensitivity to air humidity : a hypothesis for its control through peristomatal evaporation]Stomatal sensitivity to air humidity : a hypothesis for its control through peristomatal evaporation

Using the infra-red gas analysis system, the rate of CO2 uptake, transpiration, leaf conductance and water use efficiency were determined on attached leaves of cassava cv. MCol 1522 and CG 403-18, which were grown in pots left outdoors. In the stress treatment, the water was withheld from the fou...
