Abstract

Senescence is a factor limiting the marketing of most flowers and considerable effort has been applied using various treatments to increase longevity of flowers. Accordingly, a factorial experiment based on completely randomized design with two miniature carnation cultivars (Aragon and Erueka), two temperatures (2 and 4oC), 13 treatments (control treatment and various concentrations of AMINO-oxyacetic acid, BENZYLADENINE and 1-methylcyclopropene) to investigate the role of low temperature and ethylene inhibitor treatments on VASE LIFE, ethylene production levels and antioxidant enzyme activities were implemented. The cut flowers were pulsed with AMINO-oxyacetic acid, BENZYLADENINE and 1-methylcyclopropene then storage in 2oC and 4oC temperature. After 10 days of dry storage the cut flowers were inset into distilled water. According to mean comparisons the VASE LIFE of cut spray carnation in both investigated temperatures (2°C and 4°C) was 15 and 11.50 days, respectively. Among both temperatures the highest VASE LIFE was related to 6 hours of 0.72 ml L-1 1-MCP treatment. Generally, low temperature showed the significant effects on ethylene production. As, the mean ethylene productions in studied temperatures (2oC and 4oC) were 2.35 and 4.11 nl g-1 FW h-1. The maximum antioxidant activity was observed in 4°C. A significant increase in SUPEROXIDE DISMUTASE, CATALASE and PEROXIDASE enzyme activities was observed in the treatment with 1-MCP.
