Vase life and Quality of Spray Chrysanthemum (Dendranthema grandiflora ‘Tzevlev’) as Influenced by Floral Preservatives

An experiment was conducted to study the effect of floral preservatives on the vase life and quality of chrysanthemum. The seven treatments viz., T1 (AgNO3 : 75ml + Sucrose : 75ml), T2 (AgNO3 : 50ml + 8-HQC 50ml + Sucrose: 50ml), T3 (8-HQC : 75ml + Sucrose : 75ml), T4 (8-HQC : 150ml), T5 (AgNO3 :150ml), T6 (Sucrose : 150ml), T7 (Control- Distilled water : 150ml) were evaluated in Completely Randomized Design with three replications with 21 cut stems. The experimental findings revealed that the treatment T1 (AgNO3 + Sucrose) was most effective for maximum increasing in fresh weight on 3rd and 6th day, minimum reduction in fresh weight at senescence day, maximum solution uptake on 3rd day and at senescence day, maximum bud opening % on 9th day and observed maximum vase-life with this treatment.
