Abstract
Self-heal (Prunella vulgaris L.), a medicinal plant with strong antiviral activities, was regenerated from seedling shoot-tips cultured on medium containing selected concentrations and combinations of various plant growth regulators. The highest frequency of multiple shoot regeneration was obtained with 3.0 mg L−1 BA with 0.1 mg L−1 IAA. Regeneration tests with leaf lamina, petiole, stem internodes, and root explants cultured on medium containing combinations of plant growth regulators at various concentrations were unsuccessful. Regenerated shoots obtained from shoot-tips readily rooted on media containing IAA, IBA, NAA, or 2,4-D, with medium containing 3.0 mg L−1 IAA or 3 mg L−1 IBA being the most effective. Rooted explants transferred to vermiculate in Magenta boxes and acclimated for 2 weeks could be planted into foam cups containing potting soil and maintained in an environmentally controlled plant growth room.
