The interaction of pulsing in preservatives, growth regulators and cold storage on vase life and quality of Chrysanthemum (Dendranthema grandiflora) cut flowers was investigated. Chrysanthemum cut flowers were treated with benzyl adenine (BA), silver nitrate (AgNO3), cobalt sulfate (CoSO4) and sodium hypochlorite (NaOCl) and then were placed in cold storage at 5ºC for periods of 1, 2 and 3 weeks. Vase life, fresh weight, total chlorophyll and total carbohydrate were determined. Cold storage for
