Changes in root morphology and physiology to limited phosphorus and moisture in a locally-selected cultivar and an introduced cultivar of Medicago sativa L. growing in alkaline soil

摘要

The productivity of lucerne (Medicago sativa L.) is limited by phosphorus (P) deficiency and drought on alkaline soils in northwest China. The aim of this study was to identify the morphological and physiological responses of roots to P- and moisture-limited conditions in an alkaline soil.
