Regeneration of plantlets from leaf and petiole explants of Pelargonium x hortorum

“…Another group, P. peltatum hybrids, are called the ivy leafed geraniums. Among flowering plants, geraniums command a substantial portion of the market share (Horn, 1994).…”

Breeding For Ornamentals: Classical and Molecular Approaches

“…Examples can be found in pot azaleas (Heursel and Horn, 1977), Primula (Horn and Eltorkey, 1989), Pelargonium (Horn, 1994), Gerbera (Tyrach and Horn, 1997), and cyclamens (Takamura eta/., 2000). There are numerous examples in floriculture crops where genes for certain flavonols or anthocyanins can be defined in terms of the biosynthetic pathway by analogy.…”

History and Culture of Regal Pelargonium

“…The designated lectotype for the genus Pelargonium is the hoodedleaf pelargonium (van der Walt and Vorster, 1981). In a review of interspecific crossability in Pelargonium, Horn (1994) reported that species in the section Pelargonium were crossed with species in Polyactium, Hoarea, and Glaucophyllum resulting in viable seeds.…”
