Abstract: Heliconia (Heliconiaceae) species are widely commercialized by producers and consumers, due to the beauty and variety of shapes, colors of bracts, resistance to transport, and postharvest durability of their flowers stem. The purpose of this study was to evaluate the productivity and durability of bracts of three species of Heliconia spp., under different conditions of cultivation and cold storage temperatures. Heliconiaceae accessions cultivated in full sun and semi-shade were evaluated for the number of marketable stems produced and their postharvest durability under varying storage temperature conditions (16, 19, and 26 °C). Data from two years of cultivation were subjected to analysis of variance and Scott Knott's test. The productivity of flower stems was influenced by the growth conditions. H. psittacorum and H. bihai (Maluca) showed higher yields under shaded cultivation, while the highest productivity for H. densiflora was observed in full sun cultivation. Temperatures of 16 and 19 °C effectively prolonged the life of the flower stems. Shaded cultivation and refrigerated storage of Heliconia spp. are important methods to ensure successful cultivation and commercialization of these species, as they increase productivity and extend the useful life of flower stems.
