The purpose of this study is to simulate the vibration due to transportation for cut roses and then to discuss the relation between the vibration frequency, time and the effects of the cut flowers' physics and aging. The items of experiments include the weight of flowers, the rate of water absorbing, the breathing rate and the production of ethylene. Hopefully, the effects of vibration on the cut roses can be reduced.
The Grand Gala, which is a kind of local product, was chosen as an experimental material. After cutting, the roses were put into water immediately to avoid losing water. The cut roses had to send to laboratory in one and half hours. In this research, we imitate the vibration of the trucks traveling on the high way by both signal generator and shaker. Kept the cut flowers standing in the breathing cylinders with water and the constant temperature of 24℃. After sealing the cylinders, they were vibrated with the frequency of 20Hz and the amplitude of 500μm.
The weight change of the cut roses could be represented as an equation of . The results showed that the rate of weight losing for the cut flowers with vibration was fast than that without vibration. Under the vibration stress, the rate of breathing increased. It was observed that the rate of water absorbing was higher on the second day. Therefore, it was concluded that the transport-vibration indeed sped up the death of roses and shortened the life of the flowers. The main effects of cut flowers due to vibration happened on that time when the stress came, in the mean time, the rate of breathing rose, the ethylene also produced. It was to conclude that transport-vibration could have the effect on the quality of cut roses.
Key word: rose, vibration, the rate of breathing, ethylene.
