不同浓度TOG-10保鲜液对洛神玫瑰保鲜效应研究OA

By conducting experiments on the preservation effects of different concentrations of TOG 10 preservative on Roselle rose,the appropriate concentration for its application was determined.This experiment used fresh-cut rose hibiscus as the test material and was conducted under normal temperature(20 to 25℃)conditions.4 treatments were set up in the experiment including 0.5,1.0,and 1.5 mL/L TOG-10 preservative solution and a tap water control.During the vase insertion period,the vase insertion cy-cle,the change in flower diameter,the change rate of fresh weight of flower branches,and the pH change of the vase insertion solution were measured.Results showed that with the extension of the vase insertion time,the change rate of the flower diameter and the fresh weight of the flower branches of Roselle rose first increased and then decreased.With the increase of the concentration of the preserva-tive solution,both the bottle insertion life and the maximum flower diameter showed a trend of first increasing and then decreasing,and were significantly higher than that of the control.Compared with the initial flower diameter,the maximum flower diameters under the tap water control,0.5,1.0,and 1.5 mL/L treatments increased by 4.98%,4.98%,14.43%,and 6.97%,respectively.In addition,with the senescence of vase rose,the pH value of vase solution gradually decreased.Among the different preservative treatments,the 1.0 mL/L TOG-10 solution treatment resulted in the longest vase life,the largest flower diameter,and the greatest increase in fresh weight of flower branch in Roselle rose.
