CaCl2对月季切花瓶插效果的影响

目的]探讨CaCl2在月季切花瓶插过程中的保鲜效果。方法]以月季“红衣主教”为试验材料，研究在月季瓶插过程中，3种不同浓度5、10和15g／L的CaCl2对月季切花的外观品质，瓶插寿命，鲜重变化率及水分平衡值的影响，结果]结果表明，3种不同浓度的CaCl2处理，均可以不同程度地促进月季切花吸水，增大切花鲜重，维持水分平衡，延缓切花变色和弯头时间，延长瓶插寿命。其中5g／LCaCl2处理效果最好，瓶插寿命比对照延长约3d。结论]5g/LCaCl2＋蒸馏水＋200mg／L8-羟基喹啉是该试验最好的处理方法。

Study on Preservation Effects of CaCl_2 on Cut Rose

Objective ] The pureose aimed to discuss the effect of CaCl2 on the vase life of cut rose. Method] The impacts of 5,10 and 15 g/L CaCl2 on the appearance of quality, vase life, changes in the rate of fresh weight and water balance of cut-rose ＂Kardinal＂ during the vase process were conducted. Results]The results indicated that three different concentrations of CaC12 could promote water absorption,increase the fresh weight, maintain water balance, delay the time of discoloration and bending and extend vase-life of cut rose in varying levels. Of them, the effects of 5 g/L CaCl2 was the most significant, which could extend about 3 days of vase life than the control. Conclusion] 5 g/L CaCl2 ＋ distilled water ＋ 200 mg/L 8-HQ is the optimum treatmenr in the experiment.
