| Abstract:
In vitro propagation techniques have been applied to a number of Ornithogalum species. The inflorescence stalk harvested before of floral sprouting was an alternative explant to leaf and bulb. Four species of Ornithogalum (O. longibracteatum, O. thyrsoides, O. dubium and O. saundersiae) and benzylaminopurine (BAP) concentrations 1.5, 2 and 2.5 mg L-1 were tried. After 35 d, percentage of contamination, bulbs number and size of new regenerated bulbs have been recorded. Results showed very low contamination rates. The inflorescences were better explants than leaves and bulbs and the best BAP concentration was 1.5 mg L-1. The propagation system was rather efficient. | |
