In vitro Release of Axillary Shoots from Apical Dominance in Monocotyledonous Plantlets

Abstract

The following plants were used: Iridaceae, Gladiolus cv. Forest Fire, Iris hollandica cv. Wedgwood, Freesia hybrids, Sparaxis bicolor, Schizostylis coccinea; Liliaceae, Hyacinthus cv. Princess Irene, Lilium pyrenacium, Lilium hybrid, Fritillaria meleagris; Amaryllidaceae, Narcissus cv. Rembrandt, Dutch Master, King Alfred, Hippeastrum hybridum. Plantlets were cultured on a basic medium containing 6-benzylaminopurine (BAP) at concentrations ranging from 0.008-32.0 mg l-1. BAP in appropriate concentration may be used to promote steady axillary branching without callus formation. Many monocots can be multiplied and stored indefinitely in culture.
