Abstract
Effects of spraying glutamic acid (Glu), glutamine (Gln) and glycine (Gly) on nitrate accumulation and nutritional quality of pakchoi (Brassica chinensis L.) were studied both in summer and in autumn. The result showed that the three amino acids (Glu, Gln, Gly) could significantly enhance yield of shoot and Gln was found to be the best. Better gains of increased yield of shoot were obtained when the amino acids were treated in summer than in autumn. The nitrate content of shoot decreased obviously when amino acids, specially, Glu was used in the two seasons. Both chlorophyll and vitamin C contents were improved by spraying three amino acids and benefits were better in summer than in autumn, too. Of three amino acids, could increase P concentration of shoot in summer and K concentration in autumn significantly. Both Glu and Gly significantly increased Ca and Fe concentration, but all the acids significantly decreased Zn concentration in summer. Gly increased Fe concentration, and Gly and Glu increased Zn concentration significantly, but Gln and Gly decreased Ca concentration and Gln decreased Zn concentration significantly in autumn.
