Abstract
Given access to soil water at high potential the root system can generally meet evaporative demand; but under adverse conditions with relatively dry soil and high evaporative demand, supply often falls below demand and yield suffers. To extract water from the soil at a rate sufficient to match demand, gradients in water potential have to develop to overcome resistances to flow located in the soil and in the plant itself. This chapter deals with the water transfer properties of plant roots and root systems and how these modify water supply in cereals.
