Productivity and postharvest durability of Heliconiaceae grown in full sun in the Midwest region of Brazil

Flower stems of the Heliconiaceae family are gaining more and space in Brazilian market ornamental plants further knowledge about quality, productivity, postharvest management is necessary. The objective present study was to evaluate heliconiaceae cultivated full sun central-west region Brazil terms agronomic traits determine post-harvest durability floral submitted cold storage. Accessions Heliconia bihai cultivar Caribea, H. Iris Red, rauliniana were evaluated. Quantitative qualitative morphological characteristics total number flower produced marketable obtained. Postharvest longevity tested a chamber at 16 ºC 19 ambient temperature 26 ºC. Morphological such as length, diameter fresh mass stems, inflorescence inflorescences most affected. important variables quality productivity durability. studied heliconias presented characters within commercialization standards, highlighting (Caribea) which highest productivity. best storage for all accessions evaluated °C.
