Abstract/ Executive Summary:

Extended of the vase life is a crucial point of view for commercial cut flower. To improve the vase life of tuberose some preservative solution viz. T₀: Tap water (Control); T₁: Sugar (50-ppm); T₂: Citric Acid (50-ppm); T₃: Salicylic Acid (50-ppm); T₄: Chitosan (50-ppm); T₅: Silvar Thiosulphate (50-ppm); T₆: Sugar + Citric Acid (50-ppm); T₇: Sugar + Salicylic Acid (50-ppm); T₈: Sugar + Chitosan (50-ppm) and T₉: Sugar + Silvar Thiosulphate (50-ppm) were used as vase solution. Maximum floret opening (42.7%), first floret wilting (4.3 days), first petal dropping (5.3 days), solution uptake (74.0 ml), petal water content (54.3%) and vase life (9.7 days) was found from T₇ which was followed by T₆. Findings of the study indicated that carbohydrate and acidic mixture as vase solution greatly influence the shelf life of the cut tuberose.

Start Date: 00-10-2012

End Date: 00-03-2013

Program Area: Crop-Soil-Water Management

Commodity: Tube rose

Objectives:

To improve the vase life of tuberose some preservative solution

Methodology:

Experiment was conducted at 2a biotech, Department of Horticulture, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh from October 2012 to March 2013 to find out the appropriate chemical preservative solution for extending the vase life of tuberose. Equally maintained flowers were collected from Horticulture farm, Sher-e-Bangla Agricultural University. Ten chemical preservative solutions were used for vase life analysis and these were T₀: Tap water (Control); T₁: Sugar (50-ppm); T₂: Citric Acid (50-ppm); T₃: Salicylic Acid (50-ppm); T₄: Chitosan (50-ppm); T₅: Silvar Thiosulphate (50-ppm); T₆: Sugar + Citric Acid (50-ppm); T₇: Sugar + Salicylic Acid (50-ppm); T₈: Sugar + Chitosan (50-ppm) and T₉: Sugar + Silvar Thiosulphate (50-ppm) using Completely Randomized Design (CRD) with three replications. Data were collected on floret opening, floret wilting, days to floret wilting, days to first petal dropping, solution uptake, petal water content, vase life and fungal infection. Solution uptake was measured by subtracting the solution at the last days in flower vase from the initial solution of the flower vase. Petals water content (% WP) was determined with the below equation: %WP= {(FW-DW) ÷ DW} × 100. Collected data were analyzed statistically using MSTAT-C computer package program and significance of the difference among the treatment means was estimated by the Least Significant Difference (LSD) test at 5% level of significance.

Achievement/Findings:

Sugar and Salicylic Acid (50-ppm) was the best chemical treatments for tuberose flower quality and vase life which was followed by Sugar and Citric Acid (50 ppm). Based on the findings of this study it can be recommended to use sugar and acid mixture for the improvement of the vase life of tuberose.
