Chlorophyll content decreased in both control and treated broccoli florets during storage. However, chlorophyll degradation rate was significantly lower in both of fluorescent and LED green light treated broccoli florets than in control florets (Fig. 2C). The content of chlorophyll was 39.8% and 59.1% higher in fluorescent and green light treatment, respectively than those in control broccoli florets on the 2nd day.
