Vase life is one of the most important factors that determine the marketability of cut flowers and is greatly affected by the water balance. In recent years, cut hydrangea flowers are increasingly consumed as decorations for various events. However, the vase life of cut hydrangea flowers varies greatly depending on the postharvest solution management. Therefore, this study investigated the vase life, solution uptake, water balance, and relative fresh weight of freshly harvested hydrangea (Hydrangea macrophylla ‘Verena’) according to the three types of holding solutions (tap water, 1% chrysal professional Ⅲ (CPⅢ), 2% sucrose + 250 mg/L 8-hydroxquinoline + 100 mg/L citric acid (SHQC)) and the combination solutions (pretreatment; tap water, 0.1% chrysal RVB (RVB), floralife quickdip (FQ), transport; tap water, CPⅢ, floralife clear (FC), preservatives; CPⅢ, FC) for each distribution stage (pretreatment-transport-consumer). In the preservative comparison experiment, compared with the control, CPⅢ treatment and SHQC treatment significantly increased the vase life in 2019 (0.7 days, 3.4 days) and 2020 (1.4 days, 3.1 days), respectively. In the comparative experiment by solution combination, the group (RVB, FQ) using the pretreatment significantly extended the vase life by 4.6 days and 5.9 days compared to the tap water treatment. It was also determined that the same treatment increased overall solution uptake, maintained water balance longer, and increased relative fresh weight. These results confirm the importance of holding solutions and pretreatments, suggesting that appropriate pretreatments and preservatives should be used to improve the marketability of cut hydrangea flowers.

Keeping Quality

Keeping quality and length of vase life are important factors for evaluation of cut flowers quality, for both domestic and export markets. Studding the effect of pre- and post-harvest salicylic acid applications on keeping quality and vase life of cut alstroemeria flowers during vase period is the approach taken. Aqueous solutions of salicylic acid at 0.0 (with distilled water), 1, 2 and 3 mM were sprayed to run-off (approximately 500 mL per plant), about two weeks before flowers harvest. The cut flowers were harvested in the early morning and both of cut flowers treated (sprayed) and untreated were kept in vase solutions containing salicylic acid at 0.0 (with distilled water), 1, 2 and 3 mM. Sucrose at 4% was added to all treatments as a base solution. The changes in relative fresh weight, water uptake, water loss, water balance, total chlorophyll content and vase life were estimated during vase period. The results showed that the relative fresh weight, water uptake, water balance, total chlorophyll content and vase life decreased significantly while the water loss increased significantly during experiment for all treatments. A significant difference between salicylic acid and control treatments in all measured parameters is observed. During vase period, the salicylic acid treatments maintained significantly a more favourable relative fresh weight, water uptake, water balance, total chlorophyll content and supressed significantly water loss, as compared to control treatment. Also, the results showed that the using salicylic acid increased significantly the vase life cut alstroemeria flowers, over control. The highest values of measured parameters were found when plants were treated by pre + post-harvest application of salicylic acid at 3 mM. The result revealed that the quality attributes and vase life of cut alstroemeria flowers were improved by the use of salicylic acid treatment.

ABSTRACT: Aster (Aster ericoides L.) is a flower crop of North American origin, which belongs to the family Asteraceae. This plant presents capitulum-type inflorescences, widely used as cut flowers. In Brazil, it has been grown only recently, but still has a high expansion potential. In floriculture, pulsing and conditioning solutions are often used to extend the vase life of cut flowers. The present study aimed to evaluate the influence of silver thiosulphate (STS) pulsing and sucrose solutions on the postharvest life of A. ericoides stems. The experiment was carried out under a complete randomized design with treatments arranged in a 2x5 factorial scheme. Treatments consisted of flower stems treated with STS pulsing for 30 minutes, combined with four sucrose concentrations (5, 10, 15, and 20%) for six hours, plus a control (without treatment). Each plot contained four replicates of 10 stems, totalizing 400 stems. The following variables were daily: vase life, fresh mass, and relative water content (RWC). For pulsing data, means were compared by the Tukey’s test (p≥5%). Yet for sucrose concentrations, means were submitted to a polynomial regression to verify the behavior of variables as a function of concentrations increases. Likewise, each treatment was evaluated for fresh mass and RWC variations over time by a polynomial regression. Results indicated no effect of STS pulsing (2mM) on the vase-life length of aster stems. In contrast, the sucrose solution at 10% extended the vase life of stems by two days, decreased fresh mass loss, and helped maintain water balance in stems.

Abstract Quality of cut flowers is an important issue at postharvest as well as an important factor contributing to marketing of and profitability from the tuberose. In this study, the effects of citric acid (CA) and hydrogen peroxide (H2O2) added to the vase water on postharvest quality of tuberose cut flowers were investigated. CA was applied in concentrations of 50, 100, 200, 400 mg·dm−3 and H2O2 in concentrations of 10, 20, 40 and 80 mg·dm−3 and distilled water as control treatment. Results showed that both compounds had significant positive effects on solution uptake, wilting and abscission of florets, relative water content, chlorophyll content, and vase life duration. The effects of 100 and 200 mg·dm−3 of CA and 20 and 40 mg·dm−3 of H2O2 proved to be more effective than other treatments. Both compounds increased the vase life of tuberose cut flowers and CA at concentrations 100 and 200 mg dm−3 and H2O2 at concentrations 20 and 40 mg dm−3 doubled this time up to 14-17 days.

Lily is one of the prominent cut flowers on the international markets, so that its longevity is an important post-storage attribute. Blockage of xylem vessels and insufficient water uptake contributes to the short vase life of cut flowers. Bacteria block stem xylem vessels and because of that reduce rates of water supply to flowers. Nano silver has antimicrobial effects at low concentration. Prolongation of vase life cut lilies (L. orientalis ‘Bouquet’) flowers by nano-silver particles was studied. Cut flowers were kept in vase containing 5, 15, 25, 30 ppm of nano-silver solutions and deionized water as control treatment under controlled conditions. During vase period, vase life, vase solution uptake, initial fresh and bacterial numbers were measured. According to the results, all nano-silver treatments extended the longevity of cut flowers compare to control. Among these treatments the concentration of 30 ppm of silver-nano showed the highest vase solution uptake, initial fresh weight and lowest bacteria colony during the first 2 days of vase life. It was concluded that nano silver particles had a high potential for eliminating of bacterial contaminants. These for suggest that application of solutions containing superior advantageous of nano-silver particles is recommended to improve postharvest of L. orientalis ‘Bouquet’.

Abstract This study was carried out on the flowers of 'Le Castel' Dahlia (starflower) cultivated in Tokat Gaziosmanpaşa University Agricultural Research and Application Center in 2019. The study aimed to prolong the vase life of Dahlia flowers used as cut flowers. Deionized water (control), sucrose + deionized water, thyme oil, lavender oil, carvacrol, thymol, sodium hypochlorite, and gibberellic acid were used as vase solutions. The total vase solution uptake (g/stem), daily vase solution uptake (g/day fresh weight (FW)), proportional FW (%) and vase life (day) parameters were determined based on Dahlia flowers that harvested at different harvest stages (3, 4 and 5 layers). As a result; the most extended vase life was measured in the gibberellic acid treatment (8.22 days), the highest proportional fresh weight was measured in the carvacrol in the 6th day (139.78%), the highest daily solution uptake was measured in the thyme oil in 0-2 days (11.7 g/day FW) and the highest total solution uptake was measured in the thyme oil (27.5 g/stem). It was concluded that the vase life of earlier harvested flowers was longer than of late harvested.

Abstract Floriculture is a promising activity and has great economic importance. In this context, the cultivation of Lilium pumilum Redouté stands out. However, one of the main challenges flower farmers face is that a large part of the products is lost before reaching the final consumer, due to postharvest losses. Such losses can be minimized by adopting some techniques, such as the use of conditioning solution (pulsing), which has been effective in preventing early senescence. In this sense, this study aimed to evaluate the effect of pulsing with sucrose, citric acid and silver thiosulphate on postharvest conservation of L. pumilum cut flowers. All treatments promoted a 1.8±0.3 day increase in longevity, uniformity of floral opening, and reduced fresh weight loss compared to the control (flowers that were not pulse-treated). There was no significant difference in chlorophyll content and leaf relative water content. The time of exposure to pulsing caused significant differences in the reduction of anthocyanin contents when compared to the control, demonstrating that pulsing preservative solution for at least 6 h extends the vase life of L. pumilum cut flowers by two days.

Among the ornamental flowers marketed as flower vase or cut, there is Lilium pumilum belonging to the Liliaceae family, which is characterized by having several stems with inflorescences containing buds, easy propagation and varied coloring. The marketing of cut flowers is a promising activity; however the transport demands attention due to water stress, which can impair the absorption of water and rehydration, yielding a negative water balance, since the absorption rate is less than the rate transpiration. Based on this assumption, the use of appropriate techniques that allow extending the longevity of the flowers is required. This study aimed to analyze the effect of storage time on the recovery of dry turgor L. pumilum. For this flower stems were dry-stored for 0, 12, 24, 36 and 48 hours. At the end of each period, the inflorescences returned to the water, and analyzed every 6 hours for changes in relative water content of the tepals (flower), orange buds and leaves. Daily evaluations were changes of weight and longevity. The relative water content of flower there was a sharp drop during periods of dry storage, but with recovery after 6 hours in water with greater efficiency in the treatment of 48 hours, with recovery of 86.8% relative to the control. As the relative water content of the button, all treatments were recovered. Regarding the variation of fresh mass, there was variation with the period of dry storage, and only the stems that remained for 12 to 24 hours to dry obtained superior recovery for loss of initial fresh weight within the first six hours of hydration at 118.7 and 26.01%, respectively. The average longevity of the stems was unchanged (6.8 days) for no treatment. Therefore, regardless of the duration of dry storage, there was recovery of turgor, indicating that flower stems of L. pumilum can be transported dry for periods up to 48 hours.
