不同药剂处理对切花月季采后保鲜效果的影响

[目的]探讨不同药剂对切花月季采后保鲜的效果,为进一步延长切花月季瓶插寿命,提高保鲜质量,制定合理的保鲜技术提供科学依据.[方法]以月季品种玛利亚为材料,采用不同药剂对月季花枝进行保鲜处理,分别测定其瓶插寿命、鲜重变化、花朵直径、水分平衡,并分析不同药剂在切花月季衰老过程中的生理效应.[结果]与对照相比,6种药剂均可提高切花月季的瓶插寿命,不同药剂处理下最长瓶插寿命及浓度为:0.10% NaCl( 18 d)>50 mg/L 8-羟基喹啉(8-HQ)( 16 d)=50 mg/L CA( 16d)>50 mg/L SA( 14d)=0.5% CaCl2( 14d)>0.1% Vc( 12d);切花的鲜重、花径、水分平衡变化与瓶插寿命密切相关.[结论]6种药剂均能延长切花月季瓶插寿命,提高切花观赏价值,其中以0.10%的Nacl处理效果最好.

Post-harvest preservation of cut roses treated with different medicaments

[Objective]The present experiment was conducted to investigate the effects of different medicaments on post-harvest preservation of cut roses in order to enhance their vase life and improve fresh-keeping quality, and to develop an appropriate preservation technique. [Method]Effects of different medicament were observed on the vase life, fresh weight, flower diameter and water balance in cut roses (variety Rosita Vendela). Further, the physiological effects of different medicaments on aging of cut roses were analyzed. [Results]All six medicaments enhanced the vase life of cut roses compared to the control. Amongst different treatments, the longest vase life duration of cut roses was observed in 0.1% NaCl treatment (18 d), followed by 50 mg/L 8-HQ(16 d) and 50 mg/L CA(16 d), 50 mg/L SA(14 d) and 0.5% CaCl2(14 d), and 0.1% Vc(12 d). It was observed that 0.1% NaCl significantly enhanced the vase life of cut roses. The vase life was significantly correlated with the changes in fresh weight, flower diameter and water balance of cut roses. [Conclusion]The vase life of cut roses may be enhanced by using six medicaments in order to increase their ornamental and economic value.
