Effects of Pretreatment of NaOCl, Sucrose, and Benzyladenine on Vase Life and Quality of Cut Flower in Standard Chrysanthemum ‘Jinba’

This study was carried out to examine the effects of NaOCl, sucrose, and BA concentration as pretreatment solution on quality and vase life of cut flowers in Dendranthema grandiflorum ‘Jinba’. Flower diameter, fresh weight, and vase life in control and 0 mgㆍL⁻¹ NaOCl treatments decreased, and the treatment with 100~200 mgㆍL⁻¹ NaOCl was more effective in the quality and vase life. In pretreatment with 2.5% sucrose solution, flower diameter and fresh weight decreased and vase life was shortest due to the rapid leaf wilting. However, pretreatment with 0.1% sucrose solution increased the flower diameter and fresh weight, and showed the longest vase life. When more than 80 mgㆍL⁻¹ BA was treated with pretreatment solution, flower diameter and fresh weight decreased, and vase life was shortened. With pretreatment of 20 mgㆍL⁻¹ BA, the flower diameter was bigger than in the other treatments, but it was no effect on fresh weight and vase life. Therefore, it was suggested that pretreatment solution mixed with 200 mgㆍL⁻¹ NaOCl, 0.1% sucrose, and 20 mgㆍL⁻¹ BA was the most effective for the quality and vase life of cut flowers in standard chrysanthemum ‘Jinba’.
