Abstract
The seed viability, ex vitro germination, and percentage of in vitro zygotic embryo germination were found to be very low in Ensete superbum (Roxb.) Cheesman. Only 33.33% of seeds were viable, and the ex vitro germination percentage was only 5%, while the percentage of in vitro zygotic embryo germination was 33%. Somatic embryogenesis experiments produced competent callus on Murashige and Skoog (MS) medium supplemented with 2.5 mg L−1 2,4-D and 3 mg L−1 BAP from inflorescence explants. The embryogenic callus produced the maximum number of somatic embryos on MS basal medium kept in a dark chamber for 15 wk. Half-strength MS medium supplemented with 500 mg L−1 glutamine was optimal for somatic embryo germination and development of plantlets. Regenerated plants had 80 to 90% survival rate. Therefore, somatic embryogenesis can be considered as an efficient method to overcome a drastic reduction in population and to achieve germplasm conservation.
