Germination and Growth Improvement of Some Micro-Greens under the Influence of Reactive Species Produced in a Non-Thermal Plasma (NTP)

Micro-greens or sprouts are commonly used in the diet of many cultures owing to their health benefits. In this work we use a non-chemical solution method stimulate germination and growth seeds for sprouting, based on non-thermal plasma discharge (NTP). Such technology could represent an alternative not only reducing production costs growing micro-greens but also as pre-sowing slow germinating species those under draught stress. To evaluate efficiency treatments, Brassica oleracea Lepidium sativum were exposed produced atmospheric air different conditions. The strongest modifications recorded when was closed environment reactive remained high concentrations near seeds. garden cress exhibited stronger modifications, with decreasing water contact angle by up about 14%, which means increase hydrophilicity surface stimulation evaluated average stem length (9 ± 0.4)% root (38 0.5)% compared grown from untreated This indicated that interacting proved electron microscopy imaging penetrated inside seeds, activating biological pathways lead case. A noticeable influence reflected biochemical results, where analysis chlorophyll pigments strong especially intensified action species. results prove important contribution show possibility using improve these micro-greens, time even presenting treating packaged
