title: Plant regeneration from hypocotyls, cotyledons and stem segments of the C3-C 4 intermediate species Moricandia arvensis.
abstract: Techniques have been developed for the regeneration of Moricandia arvensis from complex explants. Hypocotyl segments and cotyledonary explants regenerated shoots, but the most efficient plant regeneration was from stem sections taken from in vitro grown shoots. Regeneration from these three explant types was tested on a range of concentrations of benzylaminopurine and either naphthylene acetic acid or indole acetic acid. Regeneration from all three explants was much higher on indole acetic acid than on naphthylene acetic acid and the ratio of auxin to cytokinin was also significant in determining the response of explants. Optimum regeneration was on 1mg/l IAA with 1mg/l BAP. Plants could be transferred to soil and grown to flowering in the glasshouse.
