不同配方保鲜液对康乃馨鲜切花保鲜效果的影响

为提高康乃馨鲜切花的保鲜效果,以鲜切花康乃馨马斯特(Dianthus caryophyllus L.Master)为试材,以乙醇、蔗糖、8-羟基喹啉、硝酸钙的不同混合液为保鲜液,测定不同保鲜液处理对马斯特相关指标的影响。结果表明:不同保鲜液处理在增大花径、保持鲜切花水分平衡、延缓花瓣膜透性增加、抑制鲜切花体内膜脂过氧化等方面均优于对照;其中保鲜液采用3%乙醇+3%蔗糖+200mg·L~(-1) 8-羟基喹啉+200mg·L~(-1)硝酸钙处理效果最好,相比对照能够延缓衰老进程、提高观赏价值,可以作为康乃馨鲜切花的理想保鲜液进行使用。

Effect of Different Fresh-keeping Agents on Physiological and Biochemical Characteristics of Carnation Cut Flower

In order to improve the preservation effect of carnation cut flowers ,taking carnation cut flowers(Dian‐thus caryophyllus L .Master)as plant materials ,the effects of three kinds fresh‐keeping agents on the appear‐ance indexes and physiology indexes were compared .The results showed that fresh‐keeping agents processing were better than CK .For example ,the flower diameter was increased ,water balance was maintained ,petal membrane permeability was delayed ,and plants membrane lipid peroxidation was checked .3% ethanol+ 3%sucrose+200 mg·L‐18‐HQ+200 mg·L‐1 Ca(NO3 )2 was selected as the optimal fresh‐keeping agents ,that the average flower diameter length was the biggest ,the water balance value was also the highest ,the relative elec‐trical conductivity and MDA was the least .
