- Observation Aerial biomass did not differ significantly among 15 wheat genotypes under well-watered conditions in 2015.
- Observation Total root biomass differed significantly among wheat genotypes under well-watered conditions in 2015.
- Observation Root weight density distribution differed significantly among wheat genotypes under well-watered conditions in 2015.
- Intervention effect Water deficit significantly reduced wheat aerial biomass in 2016 only.
- Intervention effect Water regimes did not significantly affect wheat root biomass in 2016 or 2017.
- Intervention effect Water regimes did not significantly affect wheat root biomass distribution in 2016 or 2017.
- Association Under water limitation, thinner low-biomass roots were more beneficial for water uptake than large thick roots.
- Association Root architecture and leaf isotope signatures together explained plant water status.
