Productivity and durability of Heliconiaceae grown under different conditions and stored under refrigeration

Abstract

Among the tropical flowers grown in Brazil, genus Heliconia (Heliconiaceae) is important to the ornamental plant market.2 Heliconiabihai, H. psittacorum, H. wagneriana, H. rostrata, and H. stricta are some of the most grown species in Brazil along with cultivars such as, H. psittacorum var. Golden Torch and Red Torch.3 Heliconia plants are widely preferred by producers and consumers alikefor their beauty, variety in shapes, colors of bracts, and postharvest durability of flower stems.4 However, there is a lack of information regarding development, planting systems, harvest and postharvest management, and the influence of these factors on the quality of these species.5 To efficiently produce and market these plants, factors such as choosing the appropriate species and varieties, availability of propagation materials and suitable structures for cultivation (climate control and planting system, fertilizers, and pest and disease management), as well as knowledge of production and postharvest techniques are essential.6
