Description
Sha Guo and co-authors report a 2023 pot study on wheat grown in dry soil. Spraying leaves with plant hormones called strigolactones was tested as a way to raise yield and save water. Roots send early signals when soil dries, and those signals help the plant use water well.
Sprayed plants triggered those root signals sooner as soil dried. Their leaves fought oxidative harm better, and roots grew larger and deeper. Under moderate drought, grain yield rose by about a third. Water use efficiency rose under both moderate and severe drought. The authors link the gains to faster drought sensing and stronger defence systems in the plant.
