This research was aimed to extend the vase life and improve the quality of cut roses ‘Marina’. This study investigated the effect of three different angles and sucrose concentration on the vase life and the quality of cut rose flowers. In first experiment, cut roses were placed in three different angles (0°, 45° and 90°) in holding solutions containing 0.5, 1 and 2% sucrose (soaking treatment), and examined the number of petals of cut roses. In second experiment, cut roses were placed in three different angles after pre-treated in 0, 1, 2 and 4% sucrose solution for 2 and 20 hours, and examined the flower diameter of cut roses. In third experiment, cut roses were examined the pigmentation, flowing response and chlorophyll contents in cut roses by three different angles after pulsing treatment (pre-treatment) in holding solution containing 2% sucrose for 2 and 20 hours. Results of this study showed that cut roses were influenced by arranging angles and sucrose concentrations. The vase life of cut roses were extended in 45° and 90° arranging angle, as compared with the control (distilled water), and the holding solution containing 2% sucrose significantly increased vase life of cut roses(P ＜ 0.05). Flower diameter of cut roses pre-treated in 4% sucrose solution for 2 and 20 hours significantly decreased (P ＜ 0.05). The pigmentation and flowing response in cut roses were beneficial in 45° arranging angle treated with 2% sucrose solution for 2 and 20 hours. Chlorophyll content in leaves of cut roses was not influenced by arranging angles. The pigmentation and flowing response of 0° and 45° arranging angles were better than that of 90 arranging angle. The vase life of cut roses in 45° arranging angle was more prolonged than that in 90° arranging angle. In conclusion, the arranging angles seem to be effective in retarding senescence of cut rose flowers.
