Somatic embryogenesis and plant regeneration of Gladiolus (Gladiolus hort.)

Summary Friable embryogenic callus and somatic embryos of 4 Gladiolus cultivars were obtained on Murashige and Skoog (MS) medium with various concentration of auxins from the following explants: corm slices, young leaf bases and whole, intact plantlets. Somatic embryos transferred on MS hormone-free medium regenerated into plantlets. All plantlets obtained through embryogenesis did not differ phenotypically from the parental clones. The embryogenic friable callus has been maintained for over 2 years in culture and has retained a very high regeneration capacity.Abbreviations 2,4-D 2,4-dichlorophenoxyacetic acid - KIN kinetin - NAA naphthaleneacetic acid - MS Murashige and Skoog Medium (1962) - E embryogenic callus - NE non-embryogenic callus
