摘要
采用4种不同瓶插保鲜剂配方对香石竹切花保鲜效果进行了比较研究。结果表明:4种瓶插保鲜剂均明显改善了香石竹切花体内水分状况,花朵开放度增大,切花瓶插寿命延长,POD酶活性提高,细胞膜透性增加延缓。处理A(3%蔗糖+200 mg/L 8-HQ+40 mg/L苯甲酸+300 mg/L青霉素)、处理B(3%蔗糖+200 mg/L 8-HQ+40 mg/L苯甲酸+100 mg/L赤霉素)、处理C(3%蔗糖+200 mg/L 8-HQ+40 mg/L苯甲酸+50 mg/L 6-BA)效果更加明显。处理A、处理B和处理C在延长切花瓶插寿命、提高POD酶活性上无明显差异,但处理A和处理C在增大花径、改善水分平衡和降低细胞膜透性方面要优于处理B。在延缓膜透性增加上,处理C的效果更佳。
The preservation effects of four kind preservatives on cut carnation flowers were studied.The results showed that the water holding,the flower diameter increasing,the vase life and the activity of POD of cut carnations were all significant improved,membrane permeability increasing were slower when cut carnations were dealt with four kinds of fresh-keeping agents comparing to the control 1.In which,the effects of three controls were better than control 2.On the vase life and POD activity,no significant differences were found among three controls.On water holding and the flower diameter increasing,control A and control C were better than control B.Control C was the best on slowing membrane permeability.
