摘要
为了筛选出一种高效、经济、无毒、无污染的月季切花保鲜剂,进行了在保鲜剂配方中添加多胺,以及对杀菌剂和无机盐的替代的比较实验研究。结果表明:由于亚精胺能够显著降低乙烯生成量,从而延缓月季切花的衰老进程,延长瓶插寿命。经筛选得到2%蔗糖(S)+200 mg/L柠檬酸(CA)+100 mg/L青霉素+0.15%Ca(NO3)2+0.1 mmol/L亚精胺(Spd)即5号配方保鲜剂可显著延缓月季切花衰老进程,瓶插寿命比对照延长近7 d,花径比对照增加1.46 cm,其各种考察参数都优于其他配方。因此,5号保鲜剂可以作为供试月季品种切花的首选保鲜液。
The consumption of cut roses is the first place among all cut flowers in China. It is necessary to develop an economical and innoxious preservation with high applicability and efficiency. With adding spermidine（Spd） and changing bactericide and inorganic salts, we studied the effects of different matching preservative treatments on life of cut rose cultivated in treated liquid, water balance, relative conductance and POD activity of cut roses. The results showed that preservative No. 5 （mass fraction of 2% sucrose ＋ 200 mg/L CA ＋ 100 mg/L penicillin＋0. 15 % Ca （NO3） 2＋0.1 mmol/L Spd） could remarkably extend the life of cut roses and obviously delay the process of senescence. Each measured parameter of preservative No. 5 was better than that of prescriptions and control. The preservative No. 5 was suggested to be suitable for cut roses.
