Floral and reproductive biology of Alpinia purpurata (Vieill.) K. Schum. (Zingiberaceae): An important tropical ornamental plant
Alpinia spp. play an important ecological role as a source of nectar in the understory of tropical and subtropical forests, where many of these species are common. The perennial species Alpinia purpurata (Vieill.) K. Schum. is native to the tropical rainforests of Asia and has been used as an orname...

| description | Alpinia spp. play an important ecological role as a source of nectar in the understory of tropical and subtropical forests, where many of these species are common. The perennial species Alpinia purpurata (Vieill.) K. Schum. is native to the tropical rainforests of Asia and has been used as an ornamental cut plant due to its lush inflorescences and post-harvest durability. The internal and external morphology, floral biology, and reproductive system of four A. purpurata cultivars were investigated in order to contribute to studies of genetic improvement of the species. The inflorescence of A. purpurata is terminal, globose, and has flowers protected by colorful and showy bracts. The white flowers are tubular bisexual. The floral anthesis of the four cultivars lasted 9 to 12 h and pollen viability was above 80% throughout the pre-flowering period in all cultivars evaluated. During anthesis, stigma and anther crest were receptive due to the presence of stigmatic fluid. Fruiting of the cultivars was observed after hand cross-pollination, whereas no fruiting was recorded in treatments involving spontaneous self-pollination, hand self-pollination or geitonogamy. Natural pollination induced low fruiting, suggesting low pollinator availability in the studied area. The obligatory xenogamy of A. purpurata is a facilitator for the development of new hybrids for the ornamental plant market. |

Alpinia spp. desempeñan un importante papel ecológico, como fuente de néctar, en el sotobosque de los bosques tropicales y subtropicales, donde muchas de estas especies son comunes. La especie perenne Alpinia purpurata (Vieill.) K. Schum. es nativa de las selvas tropicales de Asia y se ha utilizado como planta de corte ornamental debido a las exuberantes inflorescencias y la durabilidad posterior a la cosecha. Se investigó la morfología interna y externa, la biología floral y el sistema reproductivo de cuatro cultivares de A. purpurata, para apoyar los estudios de mejora genética de la especie. La inflorescencia de A. purpurata es terminal, globosa y tiene flores protegidas por brácteas coloridas y vistosas. Las flores blancas son tubulares bisexuales. La antesis floral de los cuatro cultivares duró entre 9 y 12 h. La viabilidad del polen fue superior al 80% durante todo el período de pre-floración en todos los cultivares evaluados. Durante la antesis, el estigma y la cresta de la antera fueron receptivos. La fructificación de los cultivares se observó después de la polinización cruzada manual. No se registró fructificación en los tratamientos de autopolinización espontánea, autopolinización manual y geitonogamia. La polinización natural indujo baja fructificación, lo que sugiere una baja disponibilidad de polinizadores en el área estudiada. La xenogamia obligatoria de A. purpurata es un facilitador para el desarrollo de nuevos híbridos para el mercado de plantas ornamentales.
