月季鲜切花保鲜技术研究

目的]探讨月季鲜切花保鲜技术。方法]用3种无机盐配制成的保鲜液对月季红色系列"卡尔红"进行处理,分别测定其花朵直径、外观品质、鲜重变化、瓶插寿命。结果]200 mg/L 8-HQC+2%蔗糖与3种盐类配成的保鲜剂,与单独使用8-HQC+2%蔗糖和蒸馏水相比较,可以改善花瓣状态、增进花色、提高开花级数等综合品质,增大花朵直径,使瓶插寿命延长2~4 d。3种加无机盐的保鲜剂中,0.2 mmol/LCoCl2的各项保鲜指标最好。结论]200 mg/L 8-HQC+2%蔗糖+0.2 mmol/L CoCl2处理保鲜效果好,可以作为月季切花的保鲜剂。

Study on Preservation Technology of Cut Roses

Objective]The purpose was to research the preservation technology of cut roses.Method]With preservation solution of 3 kinds of inorganic salt as treatment on the red series 'Karhong' of cut roses,the characteristics of flower diameter,appearance quality,fresh weight changes and vase life were measured. Result]Compared with the sole use of 8-HQC 2%sucrose or distilled water,the preservative of the 200 mg/L 8-HQC 2%sucrose combined with 3 kinds of inorganic could improve the comprehensive quality such as petal status,flower color and flowering progression,and could also enlarge flower diameter,along with the elongation of vase life to 2-4 d.In the 3 preservatives of different inorganic salt,the best one is 0.2 mol/L CoCl2.Conclusion]The treatment of 200 mg/L 8HQC 2%sucrose 0.2 mol/L CoCl2 presented better preservation effect,and it could be used as the preservative of cut roses.
