摘　　要：以中甘21(ZG21)、06-115两个甘蓝品种为试验材料,研究叶面喷施6种氨基酸对甘蓝硫代葡萄糖苷组分及其含量的影响。结果表明,不同种类氨基酸处理甘蓝硫代葡萄糖苷组分相同,均含有9种硫苷。氨基酸对甘蓝硫苷含量有一定的影响,半胱氨酸和甲硫氨酸显著提高06-115硫苷的总含量、脂肪族硫苷的含量和4-甲基硫氧丁基硫苷含量,其中半胱氨酸处理含量最高,比对照分别提高63.0%、69.6%和69.1%;半胱氨酸处理提高了3-吲哚基甲基硫苷含量,达到725.6μmol/kg,FW;半胱氨酸处理也显著提高了中甘21硫苷的总含量、脂肪族硫苷的含量、吲哚族硫苷含量和4-甲基硫氧丁基硫苷含量,比对照分别提高了27.2%、39.6%、15.3%和26.2%。半胱氨酸、苯丙氨酸、甘氨酸和谷氨酸处理都提高了3-吲哚基甲基硫苷的含量,其中半胱氨酸处理最高,达到292.7μmol/kg,FW,其次是谷氨酸和甘氨酸处理。Glucosinolates（GS） composition and contents were analyzed in two cabbage cultivars zhonggan 21 （ZG21） and 06 -115 by foliar application of 6 kinds of amino acid. Results showed each cabbage cultivar contained 9 glucosinolates in all treatments. Amino acids had an effect on glucosinolates contents in cabbage cuhivar. For cultivar 06-115, the total glucosinolate, aliphatic glucosinolate and glucoraphanin contents were increased significantly by cysteine and methionine treatment, Compared with CK, Foliar application of cysteine raised total glucosinolate, aliphatic glucosinolate and glucoraphanin content by 63.0%, 69.6 % and 69.1%, respectively, glucobrassicin content increased to 725.6 μmol/kg, FW in the foliar application treatments of cysteine. For cuhivar ZG21, the total glucosinolate, aliphatic glucosinolate, indolyl glucosinolate and glucoraphanin increased by 27.2%, 39.6%, 15.3 % and 26.2%, respectively in the foliar cysteine treatments comparing with control. Glucobrassicin content was the highest （292.7 μmol/kg, FW） in the foliar cysteine treatments, followed by glutamine and glycine treatment.
