“…The germistatic effect of 8-HQS that is described elsewhere [11][12][13][14] , and is readily highlighted in our experiment as higher mean uptake of preservative solution values (table 1), where the combinations of 8-HQS and Suc show highest mean uptake of preservative solution values but when Suc is applied alone caused a steep decrease in mean uptake of preservative solution value. This reflects the inhibitory effect of 8-HQS on bacterial colonization and clogging of xylem vessels in cut surface of the flower stem as reported earlier [15][16] . The flower diameter followed a similar pattern to mean uptake of preservative solution; being in maximum when both Suc and 8-HQS were present, regardless of AsA concentration.…”

Effect of Ascorbic Acid, 8-Hydroxyquinoline Sulfate and Sucrose on the Longevity and Anthocyanin Content of Cut Gerbera 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.

“…Postharvest longevity of gerbera has been extended using postharvest treatments (Abdel-Kader and Rogers, 1986;Accati, 1989;Amariutei et al, 1986;Kohl, 1968;Marousky and Woltz, 1975;Meeteren, 1978a;Nowak, 1981;Nowak and Plich, 1981;Waters, 1964) but the extent to which these treatments can improve vase life may be limited by the plant genome.…”

A broad source of Gerbera × hybrida Hort. germplasm was evaluated for vase life. Senescence mode, i.e., bending or folding of stems or wilting of ligulae was also recorded for flowers evaluated. Intensive selection was practiced to improve vase life. About 10% of the plants from a sample population were selected for having flowers with high vase life. Progeny means for vase life resulting from a topcross between these plants and `Appleblossom' were used to select five plants (about 1.5% of the sample population) whose flowers had high vase life. A diallel cross using these five plants as parents resulted in a progeny population with an increase in mean vase life of 3.4 days compared to mean vase life for the initial sample population. Increases in vase life means for days to bending, folding, and wilting were 0.3, 3.5, and 1.2 days, respectively. Plants with flowers which senesced due to wilting had the longest mean vase life before and after breeding. Changes in proportion of senescence modes were observed; bending decreased, folding and wilting increased. Frequencies of bending, folding, and wilting were compared to vase life means for 10 progenies. Proportion of bending generally decreased as vase life increased.

“…Flower petals are chemical materials used to increase the size, colour and life of a cut vase. Many flower protection products contain germicides, ethylene synthesis inhibitors, growth regulators, essential oils, antioxidants, antitransparent and other mineral and carbohydrate compounds that are necessary to extend the life of the cut flower vase [4,5]. Several attempts have been made to extend the life of the cut flower vase using commercial flower containers viz.…”

Cut flowers are used to express appreciation, affection and express emotions on various special occasions. The international trade in cut flowers has expanded in recent years and is expected to grow with the promotion and use of horticultural plants for their therapeutic benefits. Vase life is the period during which a cut flower maintains its appearance in the vase. This is a crucial factor in determining which plant species are ideal for use in floristry, with long vase life plants being considerably more desirable than short vase life plants. Chemical treatments that extend the life of vases are a major part of floristry. Adding sugars to a vase solution with cut flowers is known to delay aging and extend the life of the vase. Nano-sensors could therefore also help to extend the life of vases with cut flowers and thus enable the monitoring of ethylene concentrations in the warehouses of large growers and wholesalers. In floriculture, nanotechnology has increased yield to potential market value, particularly for essential micronutrients essential for host defence.
