The effects of 2,4-D, NAA and picloram on callus induction and somatic embryogenesis in ornamental asparagus
Languages of publication
In this study we examined the effect of 2,4-D, NAA and picloram at 1.5, 3.0 and 4.5 mg/l in MS medium on callus induction and somatic embryogenesis in Asparagus densiflorus cv. Sprengeri and Asparagus plumosus. The callus formation of both shoot tips and nodal explants from A. densiflorus after 8 weeks of culture on MS medium supplemented with NAA and picloram (1.5, 3.0 mg/l) was observed. However, callus on medium containing 2,4-D was occasionally induced. On medium supplemented with picloram shoot tip explants of Asparagus plumosus showed callus inducing capacity. After four weeks of callus culture on hormone-free medium the globular embryos were achieved. On callus induced NAA organogenesis was observed.
