Abstract

This study was conducted to evaluate the effect of different concentrations of carbohydrate solutions on chrysanthemum and to determine the vase life of chrysanthemum after treatment of carbohydrate solutions. Chrysanthemum flowers that harvested from Ranau farm were treated with sucrose, fructose and glucose solutions in the concentrations of 5%, 10%, 15% and 20% under room temperatures (25 0 C + 5 0 C). Chrysanthemum flowers that treated with distilled water were used as control in this study. The result showed that postharvest treatment of carbohydrate solutions significantly affected the water uptake and bud size of chrysanthemum flowers. The highest water uptake of flower samples was 15% fructose as the vase life of the flower samples also extended longer to 24 days. In this study, 15% fructose was the highest flower bud size compared to other three carbohydrate solutions. Treatment of carbohydrate solutions was effective in prolonging vase life of chrysanthemum flowers. Without the carbohydrate treatment, flower samples that treated with distilled water were wilt in the day of six. However, with supplement of carbohydrate solutions, vase life of chrysanthemum flowers extended more than six days. The highest extended vase life of chrysanthemum flowers was treated with 15% fructose which reached the day of 24. Extended of vase life in flower samples were different according to different concentrations in the three carbohydrate solutions. Low concentration of 5% in the three carbohydrate solutions was not effective in the supplying of nutrient for chrysanthemum flowers, while higher concentration of 20% in the three carbohydrate solutions was over supplying of nutrient to the flowers and resulted injury to the floral structure. The concentration of 15% of the three carbohydrate solutions was the most effective and suitable supplement for chrysanthemum. In this study, the results showed the most effective carbohydrate solution was 15% fructose as postharvest treatment for prolonging vase life of chrysanthemum flower.
