Üzüm Cibresinin Karanfil Çiçeklerinin Vazo Ömrüne Etkileri

Abstract

Demand for cut flowers is increasing day-by-day. There is the practice of using floral preservatives by the cut flower industry throughout the world. Currently, the use of synthetic preservatives is inevitable in the industry, but it becoming unsafe for individuals to handle them, especially with metal-based preservatives due to reported metal toxicity and environmental degradation on long-time accumulation. Therefore, natural preservatives with antimicrobial property need as floral preservatives. This research was conducted to determine the effects of grape marc extract (GME) on the vase life of cut carnation. D. caryophyllus cv. 'Baltico' was used as plant material. Plants were brought to the laboratory conditions and were placed in vases containing two different concentrations of GME (100 µL L-1, 200 µL L-1). The vase life, relative fresh weight (RFW), daily solution uptake (DSU), lipid peroxidation, proline content, and antioxidant enzyme activities were measured. As a result of the research, GME was found to be effective in the vase life and 200 µL L-1 concentration of the GME extended the vase life by 6.50 d compared to the control (distilled water). Also, it was determined that the GME was effective on the stress mechanisms of postharvest of the cut flowers. It improved the vase life by enhancing DSU, antioxidant enzyme activities, and maintaining RFW. Moreover, GME decreased MDA and proline accumulation. There is a need for new research to be carried out on GME and its effects on postharvest physiology. This research has particular importance as a waste material has been used.
