摘要: Root growth into deep soil is an important factor for stable production in wheat under drought conditions. penetrating capacity (RP) shown by pot experiments with a paraffin-Vaseline layer (PV layer) may be useful indicator estimating rooting ability of genotypes. Previously, we identified genotypes durum (Triticum turgidum L. var. durum) and bread (T. aestivum L.) diverse RP the experiments. In this study, investigated root distribution three Ethiopian landraces high RP, recent cultivars low one Japanese cultivar ‘Haruyutaka’ using: (1) pots PV layer, (2) boxes, (3) artificial field (4) normal to analyze relationship between estimated experiment development field. experiments, was evaluated number roots through (NRP). root-box distr...
