Metabolic Response of Pakchoi Leaves to Amino Acid Nitrogen
Published 2014-04-01Get full textDifferent nitrogen (N) forms may cause changes in the metabolic profiles of plants. However, few studies have been conducted on the effects of amino acid-N on plant metabolic profiles. The main objective of this study was to identify primary metabolites associated with amino acid-N (Gly, Gln and Ala...
