The current study applied electrospun fibers containing 8-hydroxyquinoline-5-sulfonic acid (8-HQS) (100, 150, and 200 mg L−1) and silver nitrate (AgNO3) (15 and 20 mg L−1) to enhance the longevity and qualitative parameters of two cyclamen cultivars. The results indicated that the vase life of the flowers treated with 20 mg L−1 AgNO3 and 200 mg L−1 8-HQS was higher than that of the other treatments (16 days). Cyclamens treated with 8-HQS (100 mg L−1) + AgNO3 (15 mg L−1) and 8-HQS (100 mg L−1) + AgNO3 (20 mg L−1) had lower polyphenol oxidase (PPO) activity than the control group. Also, it was observed that the higher phenylalanine ammonia-lyase (PAL) enzyme activity of cyclamens in the 8-HQS (150 mg L−1) + AgNO3 (15 mg L−1) treatment was longer than that of the other treatments and control groups. Treatment with 100 mg L−1 8-HQS and 20 mg L−1 AgNO3 showed higher peroxidase (POD) activity than the different treatments. This research indicated that adding AgNO3 and 8-HQS to electrospun fibers is a promising method for enhancing the longevity and maintaining the quality of these cut flowers.
