title: Regeneration of the Egyptian medicinal plant Artemisia judaica L.
abstract: An in vitro propagation system for Artemisia judaica L., a traditional Egyptian medicinal plant, has been developed. De novo shoot organogenesis was induced by culturing etiolated hypocotyls and intact seedlings on medium supplemented with thidiazuron [N-phenyl-N'-(1,2,3-thidiazol-yl) urea] via callusing at the cotyledonary notch region. Up to 16 shoots formed per seedling cultured on a medium containing 1 micro mol l(-1) thidiazuron for an optimal duration of exposure of 20 days. Regenerated shoots formed roots when subcultured onto a medium containing 1 micromol l(-1) indole-3-butyric acid. The regeneration protocol developed in this study provides a basis for germplasm conservation and for further investigation of medicinally active constituents of A. judaica.
