Abstract:

The quality of potted carnations (Dianthus caryophyllus L.) is often lowered during transportation and by indoor environmental conditions. We tested the ability of aminooxyacetic acid (AOA), benzyladenine (BA), and 1-methylcyclopropene (1-MCP) to improve post-production flower quality of potted carnation plants. Maximum plant longevity (15 days) was obtained using 0.6 µl L-1of 1-methylcyclopropene. As compared to control plants, ethylene production was significantly decreased by aminooxyacetic acid at concentrations over 100 mg L−1, benzyladenine at 30 mg L-1, and 1-methylcyclopropene at 0.6 or 1.2 µl L-1. A significant increase in ACC content was observed in 1-MCP treated potted plants compared with the control. However, the decline in 1-aminocyclopropane-1-carboxylic acid (ACC) content was observed after using 100 or 150 mg L-1 AOA. A significant increase in Superoxide dismutase, Catalase and peroxidase enzyme activities were noticed when plants were treated 0.6 mg L-1 1-MCP. Use of 1-methylcyclopropene (0.6 or 1.2 µl L-1), aminooxyacetic acid (100 or 150 mg L−1), and benzyladenine (30 mg L−1) significantly decreased H2O2 concentration and superoxide radical.
