|標題:||Effect of Storage Temperature and Duration on the Quality of Poinsettia|
Packaging and handling experiment of potted poinsettia cv. Peter Star was stored at 10℃, 15℃ and 25℃. Results showed that poinsettia is very sensitive to tempeture with different position. In bract, the color was bright at 10℃ and 15℃ and was best at 10℃. However, it turned white as the storage duration extended from three to five days and the effect of temperature on bract was more significantly. In cyathia, abscission rate was lowest at 10℃, and was next low at 15℃. Serious cyathia abscission occurred at 25℃. As storage period increased from three to five days, abscission rate of cyathia increased. Storage period resulted in cyathia abscised and had relationship with carbohtdrate consumption. High temperature consumed carbohydrate rapidly, therefore, resulted in abscission of cyathia. In the lower leaves, abscission rate was lowest at 15℃.
