Caracterização de espécies de Alpinia para uso como flor e folhagem de corte

Abstract

Among the species of tropical flowers produced in Brazil, Alpinia species of the genus stand out as cut flowers, cut foliage and ornamental plants. Cultivars of Alpinia purpurata, known as Gingers, are cultivate as cut flowers for their productivity, beauty, postharvest durability, ease of marketing, transport and acceptance in national and international markets. The Alpinia zerumbet and Alpinia sanderae species are grow for cutting vegetation, due their decorative. The objective of this study was to evaluate the potential of Alpinia species to be used as cut flowers and foliage, cultivated in full sun condition and half-shade (50% of artificially shade condition). To observe the effect in the quality and production of these. We adopted the experimental design in a factorial arragment of 6 x 2 (six cultivars x two crop conditions) in A. purpurata and 2 x 2 (two cultivars x two crop conditions) to A. zerumbet and A. sanderae, with four replications. The cultivation in half-shade condition contributed positively the clump high, clump area, shoots numbers in the clump, length, weight of flowering stem and postharvest durability. The most productive cultivars were the Red and Pink Ginger and productivity feature should be prioritized in studies. Also, the crop conditions of 50% artificially shaded contributed positively the clump high, clump projection area in A. zerumbet and A. sanderae species. For the use of Alpinia as cut foliage was observed that cut leaves from A. zerumbet stems without inflorescences present more than 30 days of postharvest durability.
