In vitro flowering of Amaranthus

In vitro flowering of Amaranthus

1988

A:PS

Shoot tip-derived plantlets of A. caudatus cv. Pan, A. gangeticus [A. tricolor], A. hypochondriacus, A. retroflexus and A. viridis flowered in vitro following 8 to 32 weeks in culture. Shoot tips were cultured on MS salts and (per litre) 30 g sucrose, 100 mg myoinositol, 0.4 mg thiamine-HCl and 8 g agar. Addition of 0.1 mg/litre NAA enhanced inflorescence production but was not necessary for flower induction. The fruits produced by A. gangeticus and A. retroflexus dehisced and their seeds dropped on the surface of agar medium, where they germinated immediately. The seedlings so derived could, in turn, give rise to inflorescences. Inflorescences could be detached from flowering plantlets and grown successfully for several months on basal nutrient medium containing 0.1 mg/litre NAA.
