Effect of different vase solution on post-harvest life of rose flower (Rosa hybrida L.)

The present study entitled “Effect of different vase solution on post-harvest life of Rose flower (Rosa hybrida L.)” was conducted at the Laboratory of Floriculture and Landscape Architecture, Pt. KLS College of Horticulture, and the Research Station in Rajnandgaon (C.G.) during the Rabi season of the year 2022-23. The experiment was designed using a Completely Randomized Design (CRD) with three replications, comprising eleven treatment combinations of citric acid and sucrose preservatives. The treatments were as follows: T0-Distilled Water (Control), T1-100 ppm Citric Acid, T2-100 ppm Citric Acid + 8% Sucrose, T3-150 ppm Citric Acid, T4-150 ppm Citric Acid + 8% Sucrose, T5-200 ppm Citric Acid, T6-200 ppm Citric Acid + 8% Sucrose, T7-250 ppm Citric Acid, T8-250 ppm Citric Acid + 8% Sucrose, T9-300 ppm Citric Acid, T10-300 ppm Citric Acid + 8% Sucrose. the study reveal that pre-treating rose flowers with a solution of 100 ppm citric acid combined with 8% sucrose (T2) is highly effective in extending their post-harvest life. This was followed by (T1) 100 ppm citric acid, while the minimum vase life was recorded in the control treatment (T0). This treatment significantly improved flowering parameters, including the number of fully opened flowers, flower opening percentage, days until the first flower wilting, and overall vase life compared to other treatments. Therefore, this solution is recommended for commercial handling of rose flowers.
