IN-VITRO PROPAGATION OF A NUMBER OF SOUTH-AFRICAN OXALIS SPECIES

Plantlets and bulbs of four herbaceous South African Oxalis species (O . reclinata Jacq., O. variifolia Steud., O. helicoides Salter and O. g racilis Jacq.) were regenerated in vitro from stem internode explants on a modified Murashige & Skoog basal medium. Phytohormone addenda wer e either 5 mg l-1 alpha-napthaleneacetic acid (NAA) and 0.5 mg l-1 6-( benzylamino)purine, or 2 mg l-1 NAA and 0.1 mg l-1 6-(furfurylamino)pu rine. Organogenesis was much better at 10-degrees-C than at 25-degrees -C. At the lower temperature, plantlets of O. helicoides flowered in v itro,
