Abstract

Maintaining quality and longevity of cut flowers is one of the critical issues in the floriculture industry, especially in cut flowers; and one of the most important problems in chrysanthemum, as one of the most popular cut flowers. Therefore, an experiment was conducted based on completely randomized design as pulse treatment with the three factors: tea extracts with 4 levels (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 to the results, the 20% tea extract treatment and 100 mg l-1 8-hydroxy quinoline sulfate treatment showed the highest vase life, petal protein, total chlorophyll, water absorption, and petal carotenoid.
