Abstract

Callus was induced on Papaver bracteatum Lindl. seedlings inoculated on Murashige & Skoog (1962) medium supplemented with α-naphthaleneacetic acid (NAA) (1.0 mg 1-1) and benzylamine purine (BA) (0.5 mg 1-1). Subculture resulted in excellent callus proliferation but no organogenesis. Shoots were regenerated in cultures grown on MS medium containing NAA (1.0 mg 1−1), BA (0.5 mg 1−1) and casein hyrdrolyzate (2.0 mg 1-1). The shoots developed into plantlets after 8 weeks of culture, and were induced to root on 1/2 MS without the addition of growth regulators. The rooted plantlets were transferred to soil after hardening.
