چکیده :

Roses are one of the most important commercial products worldwide due to their value in landscaping and their use as ornamental plants. inimizing postharvest losses in cut flowers and increasing their postharvest life, considering the high production costs and the sensitivity of the product to storage conditions and the sale of flowers and ornamental plants, is extremely necessary and important. Improving the quality and longevity of cut flowers is one of the key topics in postharvest physiology and the floriculture industry. In this study, rose cut flowers (Dolsevita cultivar) that were harvested in the commercial stage were prepared from greenhouses and immediately transferred to the nano-material laboratory of University of Tehran, Aburaihan campus. Cut flowers were treated with solutions containing 0, 5, and 10 milligrams per liter of silver nitrate nanoparticles for 24 and 72 hours, and the effect of these solutions on the longevity of the flowers was investigated. Evaluated traits included Flower Shelf life (days), Fresh Weight Reduction (grams) and Stem Bacterial Count (CFU). The results showed that the effect of silver nano particle was significant for all of the evaluated traits. The effect of time was significant only for weight loss. silver nanoparticles at a concentration of 10 mg per liter exhibited the longest flower shell life, while the control treatment had the shortest flower shelf life. Additionally, the treatment with silver nanoparticles at a concentration of 10 mg per liter also recorded the lowest bacterial count in the stem. Using silver nanoparticles at a concentration of 10 milligrams per liter can increase the longevity of cut roses.
