Do root hydraulic properties change during the early vegetative stage of plant development in barley (Hordeum vulgare)?

摘要

Background and AimsAs annual crops develop, transpirational water loss increases substantially. This increase has to be matched by an increase in water uptake through the root system. The aim of this study was to assess the contributions of changes in intrinsic root hydraulic conductivity (Lp, water uptake per unit root surface area, driving force and time), driving force and root surface area to developmental increases in root water uptake.
