In vitro induction of capitula from cotyledons of Carthamus tinctorius (Safflower)

Abstract

In vitro capitula (head-inflorescence) induction was observed in two varieties of Safflower (Carthamus tinctorius) from the inner surface of the cotyledons. Complete blooming of florets in a capitulum was observed within 55–90 days after inoculation. The pollen fertility of in vitro florets ranged from 90–95%. Embryo development was normal and a few seeds were also recovered.
