摘要： Some kinds of amino acids are the precursors of glucosinolate synthesis, such as methionine, phenylalanine and tryptophane. This paper studied the influence of different kinds of amino acids on the glucosinolates compositions and contents of Chinese kale. Six kinds of amino acids were used separately by foliar spray. They were methionine (Met), phenylalanine (Phe), tryptophane (Trp), glycine (Gly), glutamine (Glu) and cysteine (Cys). Chinese kale cultivar "Zizhi" was used in the experiment. The results showed that eight kinds of glucosinolates were identified in Chinese kale of all treatments, including 4 aliphatic glucosinolates (progoitrin (PRO), sinigrin (SIN), glucoraphanin (RAA) and gluconapin (NAP)) and 4 indole glucosinolates (4-hydroxyglucobrassicin (4OH), glucobrassicin (GBC), 4-methoxyglucobrassicin (4ME) and neoglucobrassicin (NEO)). Amino acids didn't change the glucosinolates compositions of Chinese kale. Met, Phe, Trp, Gly and Glu increased the content of total indole glucosinolates in Chinese kale by 22.68, 31.66, 25.29, 20.62 and 20.98%, respectively as compared to control. Met, Phe, Trp, Gly, Glu and Cys also increased the RAA content in Chinese kale by 23.37, 18.93, 11.23, 43.93, 31.34 and 40.58%, respectively as compared to control. Amino acids changed the glucosinolates contents of Chinese kale.
