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.

AbstractIn this study, succinic acid (0, 1 and 2 mM), malic acid (0, 1 and 2 mM), ethanol (0, 2 and 4% v/v), and their mixtures were applied as preservative solutions for cut flowers of spread carnation cv. ‘White Natila’ and their effect on the longevity, the amount of absorbed solution, malondialdehyde and chlorophyll content, cell membrane stability, fresh, and dry weight and on a visual quality was determined. A similarity in the effect of malic acid and succinic acid on dry weight and fresh weight loss were found. Ethanol positively affected most of the studied traits, including the vase life and fresh weight loss. The preservative solution containing 1 mM of malic acid and 4% ethanol resulted in the longest average vase life - 11.1 days compared to 8.9 days in the control. Malic acid showed a significant positive synergism with ethanol that makes it reasonable to combine them in preservative solutions intended to extend the vase life of cut spray carnation.

The short vase life is the major problem in the cut flower industry. This study was conducted to evaluate the role of different vase solutions and oils in enhancing the quality and vase life of lily cut flowers. Salicylic acid (SA; 300 mg L−1), citric acid (CA; 300 mg L−1), gibberellic acid (GA; 100 mg L−1), and clove oil (200 mg L−1) were used as vase solutions. These treatments were applied after pulsing with preoptimized sucrose 5%. It was found that SA (300 mg L−1) + sucrose (5%) improved the performance of cut flowers, which further increased the longevity of all tested lily cultivars up to eight days and the longest vase life by 17.6 days. The maximum change in fresh weight (5.60 g), increase in chlorophyll contents (3.2 SPAD value), highest protein content (6.1 mg g−1 FW), and increase in the activities of superoxide dismutase (SOD) (51.0 U g−1 protein), catalase (CAT) (36.3 U g−1 protein), and peroxidase (POD) (41.6 U g−1 protein), were recorded with the CA (300 mg L−1) + sucrose 5%. Among the cultivars, “Zambesi” performed best compared to “Sorbonne” and “Caesars”. The maximum anthocyanin contents (198%) were recorded in “Caesars”. In conclusion, among the different preservative solutions, SA performed best to prolong the vase life and quality of lily cut flowers.

Vase life is one of the most important factors that determines the marketability of cut flowers and is greatly affected by the water balance. The vase life of cut hydrangea flowers varies greatly depending on the postharvest solution management. Therefore, this study investigated the vase life of freshly harvested hydrangea (Hydrangea macrophylla ‘Verena’) according to the three types of preservative solutions (tap water (TW), 1% Chrysal Professional Ⅲ (CPⅢ), 2% sucrose + 250 mg/L 8-hydroxquinoline + 100 mg/L citric acid (SHQC)) and the combination solutions (pretreatment; TW, 0.1% Chrysal RVB (RVB), Floralife Quick Dip (FQ), transport; TW, CPⅢ, Floralife Clear (FC), preservative; CPⅢ, FC) for each distribution stage (pretreatment–transport–consumer). In the preservative comparison experiment, compared with the control, SHQC and CPⅢ 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 5.9 days and 4.6 days compared with the TW. These results confirm the importance of preservative solutions and pretreatment, suggesting that appropriate pretreatment and preservatives should be used to improve the marketability of cut hydrangea flowers.

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.

The effects of ascorbic acid (AsA), 8-hydroxyquinoline sulfate (8-HQS) and sucrose (Suc) on cut gerbera was studied. AsA (0, 100 and 150 mg L-1), 8-HQS (0 and 200 mg L-1) and Suc (0 and 30 g L-1) and their combinations were tested as preservative mixtures. Vase life was determined as the days until the flowers started to wilt and then dry weight and anthocyanin content were measured. The following records were analyzed at the 7th day of experiment: mean uptake of preservative solution, dry weight, flower diameter and quality score of cut flowers. The only measure improved by ascorbic acid was the flower diameter. The 8-HQS treatment increased vase life, dry weight, anthocyanin content, fresh weight, flower diameter and mean uptake of preservative solution. Sucrose decreased vase life, anthocyanin content and increased dry weight and flower diameter and mean uptake of preservative solution. The treatment containing the combination of 100 mg L-1 AsA + 200 mg L-1 8-HQS + 30 g L-1 sucrose resulted in the highest vase life but this was not significantly different from the controls. The highest anthocyanin content was noted in the 150 mg L-1 AsA treatment. The combination of 100 mg L-1 AsA + 200 mg L-1 8-HQS + 30 g L-1 Suc resulted the highest flower diameter. We conclude that AsA could improve the anthocyanin content and flower diameter of flowers and its addition to preservative mixtures based on 8-HQS could improve its effect to a limited extent.

Vase life is one of the most important factors determining the marketability of cut flowers and influenced by water balance strongly. In recent years, the consumption of hydrangeas as a cut flower has gradually increased. However, the vase life of cut hydrangea flowers is short depends on wilting. Thus, this study was conducted to determine the effects of different treatments [thymol (100, 150 and 200 mgL–1), 8-hydroxyquinoline sulfate (8-HQS) (200 mgL–1)], and their combination with and without 1% sucrose on the vase life, relative fresh weight, daily (solution uptake for 3 days) and total solution uptake of hydrangeas (Hydrangea macrophylla ‘Green Shadow’) harvested freshly. Distilled water was used as the control. Compared to the control, thymol 150 mgL–1 treatment with 1% sucrose significantly increased the vase life of hydrangeas flowers in 5.80 days (from 10.7 to 16.5 days). It was also determined that same treatment increased the total solution uptake and delayed relative fresh weight loss. These results indicated that thymol treatments in combination with sucrose can be used to extend the vase life of cut hydrangea.

Chrysanthemum indicum cultivar Sakura is one of the daisy cultivars. It is beautiful, but the vase life of cutting flowers is very short. The decrease in flower quality during storage and transportation is a big problem in the flower export. In this study, the morphological, physiological, and biochemical changes during the vase life of cutting flowers were analyzed. The effects of plant growth regulators and sucrose at different concentrations on the vase life of cut flowers were investigated. The vase life of Sakura cutting flowers includes two stages: (1) the growing and blooming of flower, (2) senescence of cutting flowers. During the growing and blooming, the color of disk flowers changed from green to yellow, and the ray flowers continued to expand the dimension leading to an increase in the diameter of the head flower. The senescence of cutting flowers was initiated by the reduction of chlorophyll content in the leaf, which was located at the base. Then, the ray flowers were discolored. In the senescence stage, the respiration rate and the content of the abscisic acid of head flower increased continuously. In contrast, the water absorption, the content of starch, total sugar, salicylic acid, auxin, cytokinin, and gibberellin decreased strongly. The treatment of 10 g/L sucrose, 2 mg/L NAA, 5 mg/L BA, and 20 mg/L salicylic acid in 24 hours extended the vase life of Sakura cutting flowers and the diameter of the head flower.

Allium Cepa L

Onion bulbs (Allium cepa L. cv. Creamgold), grown in a phytotron from seed, had a dry weight as percentage of fresh weight that decreased as growth temperatures increased from 22/16 to 33/28�C day/night. There were no significant differences between growth temperatures in the fructose, sucrose or fructan content and, although glucose content was higher at high temperatures, there was no correlation of total carbohydrate content with growth temperature. The sum of fructose, glucose and sucrose per unit tissue water was constant between temperatures, suggesting that the mono- and disaccharide content may control the bulb water content. These results, from controlled-environment tests, predict that in the field the best yield of dry weight as a percentage of fresh weight will be obtained at low growth temperatures.
