We tested the differentiation and morphogenetic capacity of floral organs of Iris ensata, I. setosa , and I. sanguinea cultured in vitro . Organogenesis through direct formation of shoots from explants, callogenesis, and floral organogenesis were demonstrated in I. ensata callus culture in vitro . These processes depended on the plant species and on the content of phytohormones in the medium. Adventitious shoots proved to develop on the basal part of the perianth tube and on the apical part of the ovary, while roots were not formed. Direct organogenesis was induced by the following phytohormones: α -naphthylacetic acid and 6-benzylaminopurine for I. ensata and 2,4-dichlorophenoxyacetic acid and 6-benzylaminopurine for I. setosa and I. sanguinea ; while callogenesis was induced by 2,4-dichlorophenoxyacetic acid. The obtained data indicate that development of adventitious structures from iris floral organs requires the presence of 6-benzylaminopurine in the growth medium. PLANT PHYSIOLOGYŠ š

“…Our results are consistent with those of previous reports. Kawase et al (1995) concluded that shoot regeneration from perianth-ovary junctions and ovaries of Japanese iris (Iris ensata Thunb.) was strongly affected by BA and NAA in the medium.…”

To improve the efficiency of iris plant regeneration, we tested the influence of several combinations of Kin and NAA in culture media on the induction of morphogenesis and the subsequent development of plantlets. The highest rates of regeneration (67%) were consistently observed in induction media containing 0.5 μm NAA and either 2.5 or 12.5 μm Kin. Developing medium containing 1.25 μm BA was optimal for high regeneration rates and a high percentage of plantlets simultaneously developing shoots and roots. Rooted plantlets were easily acclimatized and transplanted to various soil mixtures, then grown in the greenhouse. Under optimal conditions as many as 8000 plantlets could be regenerated from 1 g of cells in ≈4 months. Chemical names used: kinetin (Kin); 1-naphthaleneacetic acid (NAA); N6-benzyladenine (BA).

“…is of great importance due to its high ornamental value (Yabuya et al 1991). Plant regeneration by means of floral organ and scape culture has been reported in this species (Ichihashi and Kato 1986, Yabuya et al 1991, Kawase et al 1995. In the scape culture, I. ensata was characterized by high genotype specificity for callus, shoot and root induction.…”
