Vase Life and Quality of Cut Flower by NaOCl and Sucrose Treatment as Wet Harvesting Solution in Standard Chrysanthemum ‘Baekma’

Abstract

This study was carried out to examine the effective wet harvesting solution for development of wet distribution system in standard chrysanthemum (Dendranthema grandiflorum) 'Baekma'. The cut flowers were treated immediately in floral preservative solutions or dry condition after harvesting, and then the effects on quality of cut flower were compared. Also, we investigated the effects of NaOCl and sucrose on vase life and quality of cut flower. When the cut flowers were treated immediately in tap water, Chrysal OVB, Floralife, Hiflora solutions after harvesting, flower diameter and fresh weight of cut flower increased compared to dry condition treatment. In single treatment of 100 mg･L -1 NaOCl as wet harvesting solution, flower diameter and fresh weight of cut flower increased more than other treatments, and vase life was prolonged to 1.5 days than control. But, flower diameter and fresh weight of cut flower decreased in 0 or 200 mg･L -1 NaOCl. When the cut flowers were treated in combination solution of 100 mg･L -1NaOCl and 0.1% sucrose, the flower diameter was the largest by 9.8 cm, and fresh weight of cut flower was maintained the highest in holding solution. On the other hand, flower diameter and fresh weight of cut flower were lowest in combination solution of 100 mg･L -1 NaOCl and 2.5% sucrose. There was no difference in vase life between treatments mixed with NaOCl and sucrose. Therefore, it was suggested that treatment mixed with 100 mg･L -1NaOCl and 0.1% sucrose as wet harvesting solution was the most effective for vase life and quality of cut flower in standard chrysanthemum 'Baekma'.

Vase Life and Quality of Cut Flower by Wet Solution according to Shipping Period and Temperature in <italic>Dendranthema grandiflorum</italic> ‘Jinba’

“…Solutions used for wet storage transport include bactericides such as NaOCl, ClO 2, aluminum sulfate, and 8-hydroxyquinoline sulfate; sugars such as sucrose and fructose; ethylene activator inhibitors such as silver thiosulfate; and commercial products like Chrysal, used by itself or in combination with others (Hu et al, 1998;Lee, 2011;Lee and Kim, 2016;Roh et al, 2017;Uda et al, 2000).…”

“…Chrysal OVB promotes water absorption and flowering of cut chrysanthemums after harvest, maintaining fresh conditions for a long time. For exporting cut standard chrysanthemum 'Baekma', fresh weight is known to remain higher when Chrysal OVB is used as the wet storage solution than tap water, but there was no difference in vase life (Roh et al, 2017). ClO 2 is a bactericide that is effective in inhibiting propagation of aerobic bacteria in the solutions or sections of cut flowers Macnish et al, 2008).…”

Towards the Improvement of Ornamental Attributes in Chrysanthemum: Recent Progress in Biotechnological Advances

“…After harvest, cut flowers are usually distributed without roots, and hence are very difficult to maintain and store without losing quality. Cut flower quality is determined quantitatively by weight, stalk length, number of leaves, and flower size, in addition to qualitative characteristics such as flower color, fragrance, physical damage, disease, and freshness [ 91 ]. Unlike other horticultural crops, flowers are highly perishable, leading to significantly higher postharvest losses during the export of fresh flowers to foreign markets [ 92 ].…”

Effects of Dry and Wet Shipping Conditions on Quality, Vase Life, and Physiological Responses of Chrysanthemum morifolium ‘Baekma’ Cut Flowers

“…NaOCl for 1 day right after harvest was effective in increasing the quality of cut flowers (Roh et al, 2017). Thus, pretreatment agents such as Chrysal or bactericides are used as solutions for wet shipping of cut flowers.…”
