Stem flow mechanism of water channeling in wheat genotypes under natural field conditions. a Water captured by the wheat genotype in a plot under natural environment, the circle shows a zoom-in picture of the leaves bearing water droplets. b Movement of water droplets along the stem towards the base wetting the root zone. c Contact angle hysteresis of the abaxial and adaxial leaf surface, and stem flow water for the selected seven genotypes. CAH: contact angle hysteresis for abaxial (ab) and adaxial (ad) leaf surface, SFW: stem flow water
