In a trial, effects of different concentrations of auxins as well as
mounding and ringing on walnut stooling were investigated. Concentrations of
IBA + IAA + NAA mixture between 5000 and 7500 ppm, along with
mounding with a mixture of perlite and sand (2: 1) and base wiring of layers led
to the largest number and longest roots. The rooted layers were then lined-out successfully to the second nursery.
