“…The most common conditioning method from harvest to commercialization involves immersion in a solution. However, unlike dry conditioning, this method presents certain drawbacks that vary according to the species, including reduced postharvest quality and occupying a considerable amount of space within the cold chamber (Almeida et al 2011;Cunha Neto et al 2023).…”

Dry conditioning and sucrose pulsing are techniques used to improve the durability of flower stems. Dry conditioning helps to balance the osmotic potential of the flower stems and can be applied after harvest and transportation. The objective was to evaluate how different dry conditioning times followed by sucrose pulsing may affect the postharvest quality, durability, and physiological aspects of torch ginger flower stems. For this purpose, flower stems were collected and submitted to dry conditioning for different periods: 0-h, 3-h, 6-h, 12-h, and 24-h. Every 3 days, visual quality, percentage of true flowers, absorption rate, water content, fresh and dry weights, and colorimetric parameters were evaluated. The concentration of pigments, biochemistry of the antioxidant system, and macromolecules were analyzed. Dry conditioning for more than 12-h is not recommended as it leads to a loss of quality and durability in torch ginger flower stems and accelerates senescence. The absorption rate decreases and pigments break down after this period, while H 2 O 2 and lipid peroxidation concentrations increase. Furthermore, sugar and protein reserves are consumed during senescence. It is recommended to hydrate harvested stems immediately to avoid the negative effects of dry conditioning on postharvest quality and durability.

Ornamental plants play a fundamental role in diverse applications, from cut flower production to landscape design and space decoration. The ornamental industry, which is part of horticulture, has experienced significant advances and mobilizes billions of dollars in the global economy, being also a totally globalized market. In recent years, this industry has implemented advanced production strategies, from genetic improvement to sustainability and supply chain, promoting scientific research in various areas. However, the dispersion of knowledge has hindered the integration of the various research networks. Therefore, this article seeks to provide an overview of the scientific production in the cut flower sector, establishing a reference line for researchers, using bibliometrics as a tool to identify trends and the scientific structure of this area of knowledge. The results revealed that worldwide since 1983 there have been 975 articles focused on this productive system, gene rated in more than 69 countries by 2750 authors who published their research in 160 academic journals. Relevant research topics that are already developed and those that need a more intense and integrated research focus on the knowledge already generated were also identified.

Aesthetic attributes and easy-to-grow nature of tropical cut flowers (TCFs) have contributedto their potential for increased production. The dearth of information regarding agronomic practices and lack of planting materials are the key hindrances against their fast expansion. Unconventional high-temperature storage requirements and the anatomy of the peduncle contribute topoor vase life performance, while troublesome packaging and transport due to unusual size and structureprimarily cause post-harvest quality deterioration. Nonetheless, the exotic floral structuresconsequently increase market demand, particularly in temperate countries. This boosts studies aimed at overcoming post-harvest hindrances. While a few TCFs (Anthurium, Strelitzia, Alpinia, and a few orchids) are under the spotlight, many others remain behind the veil. Heliconia, an emerging specialty TCF (False Bird-of-Paradise, family Heliconiaceae), is one of them. The structural uniquenessand dazzling hues of Heliconia genotypes facilitate shifting its position from the back to the forefrontof the world floriculture trade. The unsatisfactory state-of-the-art of Heliconia research and the absence of any review exclusively on it are the key impetus for structuring this review. In addition to the aforementioned setbacks, impaired water uptake capacity after harvest, high chilling sensitivity, and the proneness of xylem ducts to microbial occlusion may be counted as a few additional factors that hinder its commercialization. This review demonstrates the state-of-the-art of post-harvest research while also conceptualizing the implementation of advanced biotechnological aid to alleviate the challenges, primarily focusing on Heliconia (the model crop here) along with some relevant literature on its other allied members. Standard harvesting indices, grading, and packaging are also part of the entire post-harvest operational chain, but since these phases are barely considered in Heliconia and the majority of tropical ornamentals except a few, a comprehensive account of these aspects has also been given. The hypothesized cues to nip chilling injury, resorting to different bio-chemical treatments, nano-based technology, and advanced packaging techniques, may help overcome preservation difficulties and propel its transition from niche to the commercial flower market. In a nutshell, readers will gain a comprehensive overview of how optimum post-harvest handling practices can rewardingly characterize this unique group of TCFs as the most remunerative component.
