title: Plant regeneration and thebaine content of plants derived from callus culture of Papaver bracteatum.
abstract: Plants have been regenerated from embryogenic callus cultures of two varieties of Papaver bracteatum and successfully transplanted to soil. Regeneration occurred in good yield, around 40 plants to soil within 5 months per 0.4g piece of original callus. Thebaine concentrations comparable to those in seed-grown plants were obtained in callus-derived plants. It is suggested that there is potential for mass micropropagation of P. bracteatum, which may be useful in developing agriculturally-improved lines.
