In vitro culture and plant regeneration of large flowered purslane
1995
Rossi-Hassani, B.D. | Zryd, J.P.
Culture conditions were established for callus induction from a range of Portulaca grandiflora Hook tissues. Rapidly growing calli were obtained on Murashige and Skoog medium with stem-, leaf- and sepal-derived explants. Plant regeneration via organogenesis was explant-origin dependent with hypocotyl tissues giving the highest shooting frequency. Light conditions, pH and carbon source had a pronounced effect on the percentage of explants regenerating buds and the number of buds formed. It was possible to establish stable regenerated plants in the glasshouse.
