Effects of Different Chemical Treatment on the Longevity of Chrysanthemum Cut Flowers

Chrysanthemum is one of the most cultivated nowt-es around the world to produce cut-flowers. In Iran flower producers pay much attention to this flower. Regarding the economic importance of increased longevity of chrysanthemum cut flowers, this study was conducted using completely randomized design on 153 uniform cut flowers all in the full scean phases. Chrysanthemum cut flowers were incubated in 16 treatments of preservative solutions and distilled water as control for 72 hours and then all transfered to distilled water containers.The effects of applied treatment on longevity of chrysanthemum cut flowers were evaluated using the measurement of cut flower longevity. fresh weight. [lower diameter, amount of water uptake and number of yellow leaves. The results indicated that the treatments especially with sucrose (%3) + aluminum sulfate (%0.2) silverthiosulfate (%4) -r citric acid (150 ppm), and also sucrose (%3) + aluminum sulfate (°40.2) and citric acid (l 50 ppm) significantly increased the longevity of chrysanthemum cut flowers.
