• Resumen

  • In vitro plantlets of Valeriana officinalis L. were regenerated from raceme stalk segments of a selected individual in bloom, then root cultures were grown on basal MS medium and on media supplemented with three commonly used plant-growth regulators (BAP or Kin alone or in combination with NAA), or with double sucrose amount. Root growth and anatomical structure were influenced by the medium composition. GC/MS analyses showed that biosynthetic capacity of in vitro roots was lost, or differed significantly from that of the blooming parent valerian plant.
