“…8-hydroxyquinoline citrate or sulfate (8-HQC or S), sucrose, silver thiosulfate (STS), dithiothreitol (DTE), citric acid, etc., are commonly used preservatives in Heliconia (Broschat and Donselman, 1983b;Bredmose, 1986;Ka-ipo et al, 1989;Whittaker, 1993;Malakar et al, 2019). Among these, 8-HQ salts and sucrose possess multifarious potential properties, such as antidesiccant and anti-microbial components, and the ability to maintain balanced water content.…”

“…Sarkar et al (2022) also obtained similar results for different Heliconia genotypes using 8-HQC-based holding solutions. Recently, Malakar et al (2019) evaluated the consequences of different vase solutions on the post-harvest durability and quality of Heliconia cut inflorescences available in West Bengal, India. They used silver nitrate (AgNO3): 1500 ppm, calcium chloride (CaCl2): 750 mg/L, citric acid: 200 mg/L in combination with 8-HQC: 500 mg/L and sucrose: 2%.…”

“…They also mentioned that in cut blooms, carbohydrate metabolism predominantly occurs via the EMP pathway (the synthetic conversion of glucose to pyruvate), and there is a shift towards cyanide-sensitive respiration. Additionally, sucrose not only serves as a source of carbohydrates (Malakar et al, 2019) but also helps protect the ultrastructure of chromoplasts, resulting in pigment retention (Singh et al, 2008). Sucrose also aids in maintaining water balance, keeping the bract cells turgid by influencing osmotic pressure (Halevy and Mayak, 1981).While Tjia and Sheehan (1984) mentioned that 8-HQC or 8-HQS does not have any impact on solution uptake or the elimination of microbial occlusion, Malakar et al (2019) found the beneficial impact of this germicide on extending vase life.…”

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.

“…According to the quotes cited for the topic pulse solutions, the studies focused on the use of sucrose, silver nitrate, calcium chloride, gibberellic acid, citric acid, and organic aloe vera solutions (Aloe vera barbadensis) and moringa (Moringa oleifera Lam. ), as medium of preserving flower stems Malakar et al, 2019;Sardinha et al, 2019;Shokalu et al, 2019). The hardiness of this species has also been compared with rose stems in terms of resistance to moisture loss (Leyva-Ovalle et al, 2011).…”

Global vision of heliconias research as cut flower: a review

et al. 2020

View full text Add to dashboard Cite

It is relevant to systematize the global knowledge generated about heliconia due to its economic importance in tropical floriculture and the cut flower market. The objective was to explore the results generated in scientific research related to the cultivation of heliconias as cut flower in terms of its methodological approach, research axes, and spatial distribution in terms of the contributions by country. A bibliographic search was conducted in Scopus, Web of science and SciELO based on the keywords “heliconia” and “tropical flowers”. Thereafter, a content analysis of the documents was conducted with the Nvivo software using a priori categories in terms of methodological approach, research axes, year, countries, and cultivars or varieties. The results indicate that the scientific contributions are mostly under a quantitative approach (98.1%). The investigations mainly address productive aspects (74.5%), post-harvest aspects (16.1%), market (6.7%) while industry-used products (2.5%) are scarcely addressed. The countries that make the most contributions are: Brazil (54.5%), Colombia (15.4%) and Mexico (10.9%). The most important species are: H. psittacorum, H. bihai, H. spathocircinata, H. rostrata and H. wagneriana. These results suggest conducting research to identify problems from the physiological, environmental, productive, and economic processes, as well as considering the strategies of farmers as a priority. This must be approached from paradigms where social actors (farmers), their development and the impacts of their social tasks on the cultivation of heliconias are considered the main axis.

“…Inflorescences of the Red Torch (Etlingera elatior) has a postharvest durability period of 5-10 days (Carneiro et al, 2014), shorter than other tropical plants such as Anthurium (Favero et al, 2020), Heliconia psittacorum (Malakar;Acharyya;Biswas, 2019) and Strelitzia reginae (Paula et al, 2021). This short durability of the Red Torch causes management problems and significant product losses after harvesting, and during the transport and commercialization processes (Carneiro et al, 2014).…”

Starch-based films for Red Torch ginger inflorescences postharvest conservation

et al. 2023

View full text Add to dashboard Cite

Different products have been tested to increase the vase life of cut flowers after harvest such as the biodegradable films. These products have been used in fruits since the application on the surface may provide the modification of the atmosphere around it, although, there is no information for flowers. The objective was to evaluate the effectiveness of cassava starch films as a postharvest product for Red Torch Ginger inflorescences. On the first experiment, different starch concentrations in the solution were tested and in the second experiment starch, concentrations with plasticizers and adjuvants were evaluated. The application of the biodegradable film in Red Torch stems acted as a barrier to the gases, as observed by their water absorption rate and the maintenance of fresh weight, maintaining postharvest quality up to Day 6. The visual quality was better in the inflorescences treated with 6% starch and in the films without additives. The use of 6% starch films led to lower contents of hydrogen peroxide and lipid peroxidation and higher levels of primary-metabolism macromolecules up to Day 6, delaying senescence and increasing postharvest durability. The addition of glycerol plasticizer to the different film concentrations improved the film resistance characteristics. It is recommended the use of films based on cassava starch at a concentration of 6%. The use of the adjuvant is not essential since it changed the film’s characteristics, leaving it less transparent and more viscous, hindering drying.
