- Abstract
In the current study, the effect of white light-emitting diode (LED) light on the postharvest quality of garland chrysanthemum during storage at 20 °C was investigated. Results indicated that, compared to the control, LED treatment maintained higher chlorophyll (Chl) content, as well as a lower respiration rate, malondialdehyde content, and polyphenol oxidase activity. The activity of chlorophyll-degrading enzymes, including chlorophyllase, Mg-dechelatase, chlorophyll-degrading peroxidase, and pheophytinase were also lower in the LED-treated plants. Additionally, the activity of antioxidant enzymes, such as peroxidase, catalase, and ascorbate peroxidase were higher in LED-treated plants than in control plants. Results indicated that the LED treatment maintained the quality and prolonged the shelf-life of garland chrysanthemum, and that the mechanism associated with the beneficial effect of LED lighting may be related to the maintenance of membrane integrity, enhancement of antioxidant enzyme activity, and the inhibition of Chl degradation.
