Maize lateral root developmental plasticity induced by mild water stress. I: Genotypic variation across a high-resolution series of water potentials.

Abstract excerpt

Lateral root developmental plasticity induced by mild water stress was examined across a high-resolution series of growth media water potentials (Ψw ) in two genotypes of maize. The suitability of several media for imposing near-stable Ψw treatments on transpiring plants over prolonged growth periods was assessed. Genotypic differences specific to responses of lateral root growth from the primary root system...
