Temporary growth cessation of wheat roots following defoliation

Eusun Han; John A. Kirkegaard; Kristian Thorup-Kristensen Plant and Soil 2024. doi:10.1007/s11104-024-06547-4

Other claims from this paper (3)

Intervention effect Root penetration of defoliated wheat paused for 269 °C days (20 days) after defoliation.
Intervention effect After the pause, wheat root penetration resumed at a rate similar to un-defoliated plants (1.8 mm °C days −1).
Intervention effect Defoliation was associated with reduced water and N uptake of wheat at maturity, especially from deeper soil layers (>2 m).
