【摘要】 将非洲菊切花在1℃和常温(15℃~20℃)下干藏3 d,以模拟运输过程,分析了有无冷藏装置对非洲菊切花流通后瓶插寿命的影响。切花的呼吸强度随着温度的降低明显地下降,2℃下的呼吸强度是常温时的1/7。经历两种温度流通后的切花瓶插寿命分别为10 d和8 d,低温使瓶插寿命延长了2 d。实验对切花瓶插期间鲜重、花径等外观品质指标,可溶性蛋白含量和可溶性糖含量等理化指标进行了测定。通过实验比较,明确了切花采后运用冷链是十分重要的。更多还原

【Abstract】 The cut Gerbera was dry stored at 1 ℃ and under the natural conditions(15 ℃～20 ℃) for 3 days.Respiration rate of the cut flowers decreased with the temperature decreasing.Respiration rate at 2 ℃ is one-seventh of that at normal temperature.Vase life after two kinds of storage was 10 days and 8 days respectively,and cold chain prolongs the vase life by 2 days.The main apparent quality parameters such as the fresh weight,span of the flowers,and the main physiological indicators such as the contents of the solute protein and the solute sugar were measured.By comparison,the importance of cold chain after cut flowers harvested is significant.更多还原
