“…The amount of soluble carbohydrates also affects the vase life of flowers (Eason et al, 1997;Ichimura et al, 2016;Shimizu and Ichimura, 2005). Soluble carbohydrates are a necessary substrate for respiration, cell-wall components, and pigments, as well as a signal for gene expression in some cases (Lewis et al, 1995;Norikoshi et al, 2016;Yamada et al, 2009). However, they also act as osmotica, with an increase in sugar concentration largely contributing to a decrease in osmotic potential, which may facilitate the influx of water into cells to maintain the pressure potential, leading to petal cell expansion and flower opening (Norikoshi et al, 2016;Yamada et al, 2009).…”

Cut dahlia (Dahlia variabilis) flowers have recently become popular in Japan, but have the disadvantage of only having a short vase life. Here, we sought to clarify which factors are responsible for this by investigating the effects of an antibacterial (CMIT/MIT) treatment and a combined glucose plus antibacterial (Glc + CMIT/ MIT) treatment on the vase life of the cut flowers of 10 dahlia cultivars, as well as the bacterial growth kinetics in their vase solutions and the soluble carbohydrate contents of their petals. We found that the CMIT/MIT treatment extended the vase life of 'Kamakura', 'Magic Pink' and 'Purple Stone', all of which had relatively high numbers of bacteria in their vase solutions. By contrast, the Glc + CMIT/MIT treatment significantly extended the vase life of three cultivars and also increased the fresh weight of nine cultivars. A comparison of two cultivars with relatively long and short vase lives ('Moon Waltz' and 'Port Light Pair Beauty', respectively) showed that a longer vase life was related to a higher carbohydrate content in the petals. Together, these findings suggest that maintaining the carbohydrate level is important for extending the vase life of cut dahlia flowers.

“…Sucrose is often used to extend the vase life of cut flowers (Halevy and Mayak, 1979;Ichimura and Hisamatsu, 1999;Nichols and Ho, 1975;Ranwala and Miller, 2009). Norikoshi et al (2016) reported that in cut rose flowers sucrose treatment increases glucose and fructose concentrations in the vacuole, which may reduce the osmotic potential of the symplast and increase water uptake leading to cell expansion during flower opening. Sucrose treatment extends the vase life, and gene expression, of sucrose transporters and invertase is involved in maintaining quality in the petals of cut peony (Xue et al, 2018).…”

Effects of Trehalose and Sucrose on the Vase Life and Physiology of Cut Astilbe (Astilbe × arendsii Arends) Flowers

et al. 2019

The postharvest physiology of cut astilbe inflorescences (Astilbe × arendsii), which consist of many small florets with a short vase life, was studied in response to treatments to extend their vase life. Exogenous ethylene treatment at 0.3 μL•L −1 for 7 h did not affect the senescence of inflorescences or leaves of five cultivars and 0.2 mM silver thiosulfate for 2 h did not improve the quality of inflorescences of three cultivars, which indicated that ethylene is not a critical factor for senescence in astilbe florets. Continuous treatment with 2% sucrose or 2% trehalose solutions prolonged the cut inflorescence vase life of one or two of five astilbe cultivars, respectively. Pulse treatment with 2% trehalose in combination with 6% sucrose increased total soluble sugar contents from 11.4 to 57.6 mg•g −1 FW and raised the respiration rate of inflorescences from 15.3 to 28.4 μmol CO 2 •h −1 •g −1 FW at 2 days after harvest (DAH) in the cultivar 'Gloria Purpurea'. However, the effects of pulse treatment diminished at 4 DAH and extended the vase life from 4.0 days to a maximum of 5.6 days, which suggested that pulse treatments were inadequate to maintain sugar contents and respiration activity. Continuous treatment with 6% sucrose extended the vase life from 4.3 to 10.0 days and raised the chroma (C*) value of florets from 28.7 to 54.9 at 8 DAH. Continuous treatment with 2% trehalase + 4% sucrose markedly prolonged the vase life to 11.5 days and increased the C* value to 53.9 at 8 DAH. Under stereomicroscopic observation, continuous treatment with 2% trehalase + 4% sucrose maintained more vivid pink color of petals, styles, filaments and receptacles than those in control florets at 9 DAH. Combined treatment with 2% trehalose and 30 μM validamycin A, a potent inhibitor of trehalose metabolizing activity, induced severe wilting of florets and necrotic spots on leaves. Exogenous trehalose may be hydrolyzed by trehalose metabolizing activity in cut astilbe inflorescences. The results suggest that continuous treatment with trehalose and sucrose solutions is effective to maintain development and delay senescence of florets to extend the vase life of cut astilbe inflorescences.

It had as objective to evaluate the effect of 8-hydroxyquinoline and chlorine, isolated and mixed in and conservation of the stem stick of the emperor. Twenty of the stem torch ginger (Etlingera elatior), variety Red Torch were harvested, transported, and immersed in standardized solutions containing biocides for 48 hours. The biocide used were 100 mg L -1 of chlorine; 250 mg L -1 of 8-(HQC); 500 mg L -1 of 8-(HQC) and 50 mg L -1 of chlorine + 50 mg L -1 of 8-(HQC), the control corresponded to water. The stems stay immersed in water for nine days at 20 ± 4 ºC. Every 24 hours, the water in the container was replaced. During nine days, some measurements were realized of pH of the water in which the stems stay immersed, in the same way, it was measured the consumption/loss volume of the water for each 24 hours in the containers. The stems were weighed and also samples were taken from the base of the stems and pear ligule determination of peroxidase activity. In general, the use of solutions of 8-(HQC), 250 and 500 mg L -1 , make easier the flux of water in the vases, measured by the consumption of water; provided lower peroxidase activity at the base, independent of the pH of the solution and maintained lower peroxidase activities in the ligule. Thus, with the results obtained, it demonstrated promise the use of 8-(HQC), in the highest concentrations tested (250 and 500 mg L -1 ) for quality maintenance of cut stems of Etlingera elatior, variety Red Torch.
