Effect of Hydropriming and Light Quality Treatments on Sprout Growth and Antioxidant Activity in Brassica oleracea var. capitate Seeds

In this study, we assessed the effect of hydropriming and light quality treatments on antioxidant activity bioactive compounds in Brassica oleracea var. capitate sprouts. B. seeds were soaked distilled water treated with different wavelengths or complete darkness for 24 h at 20 ± 1°C. Subsequently, dried h, sown sprouting trays, then incubated seven days 25 2°C under a 16/8 light/dark photoperiod white LEDs. The final percent germination sprouts was 82.3–95.7%. fresh weight shoot length increased significantly all when compared to control (soaked no drying). We tested solvents extracting determined their radical scavenging found that 80% ethanol best solvent. Hydro-primed exhibited significant differences between treatments. particular, blue treatment resulted total flavonoid content DPPH (RC50) 157.2 mg naringin equivalent (NE)·g-1 1.27 mg·mL-1, respectively, most effective increasing activity. Therefore, combined pretreatments induced changes
