Effects of Hinokitiol, Humic acid, Sucrose, and Silver thiosulfate (STS) as a Short-Time (Pulsing) Treatment on Vase Life of Cut  Yelloween Lily Flowers

In order to investigate the effects of Hinokitiol (0.1, 1, 5 and 10 Micromolar), Humic acid (100, 500. 1000 and 10000 ppm), Sucrose (2.5, 5, 7.5, and 10 percent), and Silver Thiosulphate (0.25, 0.5, 1 and 2 mM) treatments on longevity and some quality characteristics of cut yelloween lily flowers, an experiment was conducted in the form of a completely randomized design of two replications (time) in the Postharvest Laboratory of Mohaghegh Ardabili University. The results indicated that Silver Thiusulfate at o.25 to 1 mM increased the vase life of cut lily as compared with control and other treatments. Hinokitiol at 5-10 Mm decreased the vase life of the flower up to 2.4 days. The applied treatments, except for their higher concentrations, increased the uptake of in-vase solution, maintaining their relative fresh weight. Humic acid, a substitute with Cytokinin-like activity, markedly extended leaf longevity. In other words, a pulse treatment of the flower with 1000 ppm humic acid was found out as the most suitable treatment in preventing the flower from leaf yellowing under the general experimental conditions.
