| Summary: | 碩士 === 國立中興大學 === 農業機械工程學系 === 87 === Most products of the cut flowers need to be transported from the producing place to the market-place for selling; however, to the cut flowers, transporting is one of the disadvantageous operation because when the cutting flowers are boxed up, the worse surroundings, and the acts of moving and transporting might cause the vibratile damages. But there is no information show that the vibration effects indeed caused the cut flower's quality inferior. Based on using the vibration's testing machine to simulate the vibration of the vehicle on highways. Based on the above, this study decides to discuss the effects of the vibration to the cut flowers' qualities; thereamong, the effects are including the cutting flowers' variation of fresh weight, respiration rate, the producing quantity of the ethylene, and etc.
The experimental cut flowers of this study were provincial red "Dianthus caryophyllus". Put the cut flowers into the respiration vat erectly, vibrated it with 20 Hz frequency for 4 hours continuously, after vibration still put it in the vat for 2 hours. Duration the experiment, it took data in every 2 hours.
The results showed that the wilted time of the flowers treated with vibration were earlier, and the loss rate of fresh weight was larger than that without such treatment. Duration the vibration, cut flowers' respiration rate rose conspicuously, and in the beginning of vibration the influence was largest. The more vibratile time, the lower respiration.
After vibration, the ethylene of some flowers could be detected. The ethylene of the flowers vibrated could be measured at 6th days, while the ethylene of the flowers without vibrated could be measured at 7th days. All the flowers treated with vibration produced higher quantity of Ethylene than that without such treatment. Thus, cut flowers' vase life could be reduced due the vibration.
