水杨酸对香石竹切花的保鲜效应研究

Study on the Fresh-keeping Effects of Salicylic Acid on Cut Carnation Flower

以蔗糖20 g/L+8-羟基喹啉柠檬酸盐200 mg/L+硝酸钙1 g/L为基础液,分别与不同浓度的水杨酸配制成6种保鲜剂,研究了水杨酸对香石竹切花的保鲜效应。结果表明:6种保鲜剂处理均可以促进香石竹切花开放、花枝吸水、增大花径和维持切花水分平衡。水杨酸最佳浓度为40 mg/L。

Six preservatives were prepared including 20 g/L sucrose, 200 mg/L 8-HQC, 1 g/L Ca （ NO3 ） 2 and different concentration of salicylic acid （SA） to study the fresh-keeping effects of SA on cut carnation flower. The results showed that the six preservatives could promote blossom and water adsorption, increase the flower diameter and maintain the water balance. The optimum concentration of SA was 40 mg/L.
