Sequential light programs shape kale ( Brassica napus ) sprout appearance and alter metabolic and nutrient content

摘要: Different light wavelengths have specific effects on plant growth and development. Narrow-bandwidth light-emitting diode (LED) lighting may be used to directionally manipulate size, color metabolites in high-value fruits vegetables. In this report, Red Russian kale (Brassica napus) seedlings were grown under conditions analyzed for photomorphogenic responses, pigment accumulation nutraceutical content. The results showed that genotype responds predictably darkness, blue red light, with suppression of hypocotyl elongation, development pigments changes metabolites. However, these relatively hypersensitive far-red leading uncharacteristically short hypocotyls high accumulation, even after very low fluence rates (<1 μmol m−2 s−1). General antioxidant levels aliphatic glucosinolates are elevated by treatments. Sequential treatments applied throughout sprout alter final product quality. These indicate sequential treatment narrow-bandwidth affect key economically important traits crops.
