| 摘 要： | 为防止Ag+污染环境，开发适宜于切花菊运输前的不含Ag+的预处理剂及预处理方法十分必要。笔者用不同浓度(0~2000 ml/L)无银杀菌剂——苯扎溴铵对切花菊‘神马’的鲜切花进行了不同时间(0~24h)的预处理，然后插入盛有自来水的瓶内，放在温度为20~25℃室内，调查保鲜效果。与其他预处理相比，在100 ml/L溶液预处理3h，瓶插后鲜重一直呈缓慢上升趋势；6d后，极少数叶片发生萎蔫，叶片黄化速度也很缓慢，约90％的叶片12d后还可以保持新鲜；花蕾开放速度也缓慢，15d后仅有50％的花蕾开花，且花瓣挺阔，无枯萎迹象，而且茎干挺直，不弯颈；保鲜效果明显高于其他的预处理。由此可见，使用100 ml/L的苯扎溴铵溶液对菊花鲜切花进行3h的预处理，对其贮运有良好的保鲜效果。

| Abstract: | In order to prevent environmental pollution from Ag+, it is necessary to develop a pretreatment solution without Ag+ for cut chrysanthemum. Having pretreated the cut flowers in different concentration of benzalkonium bromide (a germicide without Ag+) for different times, then transplanted into water and kept in the room at 20~25℃, we investigated the effect of benzalkonium bromide on preservation. Compared with other methods, the effect on preservation of the cut flowers, pretreated in 100 ml/L benzalkonium bromide for 3 hours, was obvious. The fresh flower weights increased slowly, few or none leaves were wilting after transplanted into water for 6 days. Etiolation of the leave slowed down and almost 90% leaves kept fresh after 12 days. The flower buds blooming speed also slowed down, 50% of flower buds were opened, petals were kept fresh, the stems of cut flower were unbent, and none flowers were drooped after 15 days. These results indicated that the cut flowers after pretreated in solution with 100 ml/L benzalkonium bromide for 3 hours, the vase life extended further than the other pretreatments. |
