Studies Regarding Treatments of Led-s Emitted Light on Sprouting Fagopyrum Esculentum Moench



The present study presents the influence exercised by LED (light emitting diodes)-s emitted white (W), red (R), blue (B) light on sprouting of buckwheat seeds and evaluated the effects on content of phenolic compounds, antioxidant capacity and flavonoids.The fresh weight of hypocotyls, showed that the R light has generated the best influence for sprouts and W light has generated the most adverse influence. The content of flavonoids was stimulated by R LED for variant sprouts with testa (V3), while both B and R LED inhibited for variant without testa (V4, V6). The higher concentration of polyphenols was obtained for V5 variant illuminated with B LED and increased for V4 variant illuminated with R LED. The antioxidant capacity was higher for V3 variant illuminated with B light and stimulated by R LED in V4 variant.The results contribute to the establishment an efficient working protocol, for obtaining sprouts from buckwheat seeds, with a comprehensive content of bioactive components, various nutrients by applying the R LED treatment.
