Development of secondary inflorescences and in vitro plantlets from inflorescence cultures of Amaranthus paniculatus

Abstract

Immature inflorescences of Amaranthus paniculatus were used as explants for in vitro culture studies. When placed on a medium supplemented with 3-6 mg/l kinetin, explants developed into secondary inflorescences. Leaves and shoots developed following culture of inflorescence tissue on media containing 8-15 mg/l kinetin or 5-10 mg/l BAP. These shoots when subcultured on MS medium supplemented with 12 mg/l kinetin+15% coconut milk, formed roots. These rooted plantlets later flowered in vitro.
