Ixia viridifolia (ixia) and a new hybrid Gladiolus × Homoglossum (GH hybrid) were propagated by in vitro techniques. From an original 10 and 20 corms of ixia and GH hybrid, respectively, up to 1000 plants could be produced in 1 year. Large numbers of buds developed on transversely-cut halves of the corms when they were placed on Linsmaier-Skoog medium containing benzyladenine. Transfer to medium containing naphthaleneacetic acid resulted in elongation of buds into shoots and formation of corms at the bases of the shoots. Dormancy of the plants in vitro was dependent on the hormone composition of the medium.
