BackgroundThe role of roots in determining the yield of a crop in water-limited environments (drought resistance) is controversial as individual root traits for water uptake do not necessarily guarantee a root system is efficient at capturing soil water. For increased drought resistance do we need deep or shallow root systems?, more or less roots?, high or low root resistance?, prolific root branching or restricted branching?, high sensitivity or low sensitivity to water deficits?ScopeThe root… CONTINUE READING
