“…Flower stems of Etlingera elatior cv. 'Porcelain' were harvested at a semi-open stage in relation to the inflorescence aperture point, selecting those without true flowers (Mattos et al 2018). The flower stems were obtained at the Federal University of Lavras, in the Ornamental Plants sector, responsible for cultivating tropical flowers.…”

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.

“…One of the main problems in the commercialization of cut flowers is the reduction in vase life due to senescence and wilting (Sonego and Brackmann, 1995). Wilting results from water stress caused by transpiration rates exceeding water absorption rates, leading to loss of visual appeal (Mattos et al, 2018). Therefore, given the success of various coating films in fruit conservation (Romanazzi and Moumni, 2022), the possibility of using this technology in the conservation of cut flowers has been sought.…”

“…The reduction in respiration, transpiration, ethylene biosynthesis, and microbial growth helps maintain the quality and longevity of cut flowers. This effect can be enhanced when associated with antioxidant, antimicrobial, and other beneficial substances for the vase life of cut flower stems (Mattos et al, 2018).…”

The ornamental plant sector is growing due to the development of new species and technologies. The focus of research is to extend the shelf life of cut flowers to maintain quality and customer satisfaction. Techniques such as storage at low temperatures, use of preservative solutions, and new technologies such as nanotechnology can help maintain the quality of the floral stem. The present review aims to analyze various techniques used to extend the post-harvest shelf life of floral stems. For this purpose, a systematic search was conducted on major indexing platforms for studies published in 2023, which were subjected to a meta-analysis. The global effect size and moderator effects were calculated to assist in decision-making for future studies in floriculture. The results indicated that the addition of preservatives to solutions, variations in storage temperature, and the use of electromagnetic fields were the most effective techniques in extending the shelf life of cut flowers. However, techniques such as dry conditioning and the use of coating films did not show significant results in maintaining commercial quality. It was found that conservative solution research is still the main focus of research at major cut flower technology centers. The meta-analysis highlights the importance of further deepening and/or improving research on techniques that have shown less effective results, and developing new technologies to prolong the vase life of floral stems in order to improve post-harvest quality.
