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