Comparison Tea Extract, 8-Hydroxy Quinoline Sulfate and Rifampicin on the Vase Life of Cut Chrysanthemum (Denderanthema grandiflorum L. cv. Purple)

Maintaining quality and longevity of cut flowers is one of the criticalissues in the floriculture industry, especially in cut flowers; and one of themost important problems in chrysanthemum, as one of the most popular cutflowers. therefore, an experiment was conducted based on completely randomizeddesign as pulse treatment with the three factors: tea extracts with 4levels (5, 10, 20, and 40 %), 8-hydroxy quinoline sulfate with 4 levels (100,200, and 400 mg l-1), and rifampicin with 3 levels (100, 200, and 400 mg l-1)on spray chrysanthemum (cv. purple) with three replications. according tothe results, the 20% tea extract treatment and 100 mg l-1 8-hydroxy quinolinesulfate treatment showed the highest vase life, petal protein, total chlorophyll,water absorption, and petal carotenoid.
