Abstract: An efficient regeneration protocol was developed through direct shoot regeneration from leaf explants of Zamioculcas zamiifolia Engl . The results showed no adventitious shoots were visible from leaf explants cultured
for 8 weeks on the mediumonly supplemented with 6-BA , NAA or 2 ,4-D. Adventitious shoot differentiation could occur directly from leaf explants cultured for 3 weeks on MS medium supplemented with 6-BA 1.0 - 2.0 mg/ L and NAA 0.02 - 0.2 mg/ L. MS medium supplemented with 6-BA 2.0 mg/ L and NAA 0.02 mg/ L was most effective. The regenerated shoots rooted in the MS medium with IBA (indole butyric acid) 0.5 mg/ L.
