Studying root water uptake of wheat genotypes in different soils using water delta O-18 stable isotopes

摘要

The ability of plants to access water and nutrients is a key aspect of crop production and it is mainly through modified root growth that plants can optimize their access to those resources. Although genetics play a main role in shaping root traits, other factors such as soil physical characteristics and the distribution of water and nutrients in the soil profile can also modify root architecture.
