Fig. 2

Emission spectrum of cold plasma used for the treatment of Giza-18 seeds. Arrows above each peak indicate the expected functional role of the corresponding plasma free radical species in generating reactive oxygen and nitrogen species (RNOS), including OH• radicals, excited oxygen (O*), and nitrogen (N) states. IR: energy tail contribution.
