Water loss from roots back into drying soil is a problem of practical importance in plants growing under conditions of very low substrate water potential, such as dry or saline areas.

The relative water retention ability was compared in root segments from exodermal (maize, onion, sunflower, Rhodes grass and sorghum) and non-exodermal species (
