Abstract
Genus Vriesea of the Bromeliaceae family are highly appreciated to use as ornamental plant due to their floral morphological characteristics, color and the beauty of inflorescences. V. incurvata has been commercialized as a potted ornamental plant. The morphological features of its floral scape may also indicate it for use as a cut flower. However, there are no information available to use of this bromeliad as a cut flower. The aim of this study was to determine quantitative and qualitative criteria in order to evaluate the postharvest behavior of V. incurvata floral scapes. It was observed that V. incurvata floral scapes has great potential to use as cut flower, which has an average of vase-life of 14.9 ± 1.5 days. Quantitative and qualitative characteristics such as color (L*, C*, H°), brightness, turgidity, stiffness, presence of injuries, relative fresh weight, water uptake and loss can be indicated as postharvest evaluation criteria of V. incurvata floral scapes.
Highlights
Vriesea is a genus of bromeliads having 188 species (SMITH and TILL, 1998)
According to Yamada et al (2003), the increase of vase-life is the main goal researched in cut flowers
Results of these studies showed that V. incurvata floral scapes kept in a postharvest room with a temperature of 20 ± 2 °C and relative humidity of 80 ± 3% showed longevity of 14.9 ± 1.5 days, and it corresponds to the stage IV of the senescence scale (Figure 1; and 2)
Summary
Vriesea is a genus of bromeliads having 188 species (SMITH and TILL, 1998). These species have dispersion centers in the regions of South America, Central America and Caribbean. Vriesea incurvata Gaudich is native species of Brazilian Atlantic Rainforest This species is epiphyte with green, smooth and without spines on the leaves, arranged in the form of rosettes and with red inflorescences (REITZ, 1983; MARTINELLI et al, 2008). The prospection of new ornamental plants, from native species, represents a great potential of production and commercialization (HEIDEN et al, 2006) In this sense, V. incurvata has great potential due to their strong ornamental and landscape appeal. On the Paraná Coast Brazil, V. incurvata is considered as one of the ten most identified and commercialized bromeliads (NEGRELLE and ANACLETO, 2012). This bromeliad has been commercialized basically as a potted plant. Having their aesthetic characteristics of inflorescence, it can be considered a cut flower
