摘要：
Drought adaptation of wheat is one of the most significant and complex subjects in the rain-fed agricultural regions of West Asia. Interaction between root water-uptake and the remaining soil moisture is a key factor for drought adaptation. Under controlled conditions, root development was compared among four wheat genotypes under water deficit stress in relation to water-uptake. In addition, the effects of soil water deficit on the production of biomass and grain were examined using drought-adaptive varieties from different sources.
