Influence light-emitting diode (LED) light on antioxidant activity of radiated pea seedlings was first studied using red (625-630 nm) and blue (465-470 nm) LED lights as light sources in an attempt to determine and compare the changes in chlorophyll and B-carotene contents, and Trolox equivalent antioxidant capacity (TEAC, uM). After radiation for 96 h, comparing to white light group, red light radiated seedlings displayed significant (p
