Effects of Different Chemical Solutions on Postharvest life of Shiraz Cut Narcissus tazetta L. Flowers

Narcissus tazetta L. is one of the bulbous cut flowers native in the southern regions of Iran and cultivated most extensively in Shiraz. Due to its beauty, delicate fragrance, and due to being a bunched flower, it is superior to the other species for Iranian consumers. In order to study the effects of some chemical pulse solutions on the postharvest life of cut Narcissus, a factorial experiment was carried out in a completely randomized design with eight replications in 2002. Chemical treatments were: Silverthiosulphate, Silver nitrate, Hydroxyquinoline citrate (each in 3 concentrations) as well as tap water as control. Silverthiosulphate, Silver nitrate and Hydroxyquinoline citrate increased the postharvest life. Silverthiosulphate, in addition, improved the general appearance of wilted florets in the cluster. In total, Silverthiosulphate was found out to be the most suitable treatment.
