Effects of OLED as light source to the growth and antioxidants-concentration of broccoli sprout

Abstract

Organic light-emitting diode (OLED) is considered the next generation artificial light source after LED. However, no research was conducted using OLED as light source for plant growth. This study demonstrates the potential of OLED as the light source for sprout production. An experiment was conducted to grow broccoli sprout using OLED and LED as light source for comparison. The sprouts, grown for 5 days, provided with PPF at 105 μmol.m-2.s-1. The results show that there are no significant difference on fresh mass, vitamin C, total phenols and anthocyanin. However, there is significantly improvement on DPPH scavenging capability for those grown under OLED. OLED can be used to grow sprouts with preferred features for healthy diet.
