摘要
研究叶面喷施甲硫氨酸(Met)和茉莉酸甲酯(MeJA)单独和混合处理对芥蓝体内硫代葡萄糖苷(简称硫苷)组分及其含量的影响,为栽培调控提高芥蓝品质提供理论依据。结果表明:各处理芥蓝体内硫苷组分相同,均含有8种硫苷;Met处理对芥蓝总硫苷含量及各组分含量均无显著性影响;MeJA、Met+MeJA处理显著提高总硫苷、吲哚族硫苷、吲哚甲基硫苷和1-甲氧基吲哚甲基硫苷含量,其中MeJA处理含量较高,分别为对照的2.55,16.59,11.85和86.37倍,MeJA、Met+MeJA处理也显著降低了脂肪族硫苷、2-丙烯基硫苷、4-甲基硫氧丁基硫苷和3-丁烯基硫苷含量,其中MeJA处理较对照分别降低了32.53%,29.79%,46.71%和33.31%,Met+MeJA较对照分别降低了37.04%,37.58%,46.44%和39.36%。可见,茉莉酸甲酯可显著改变芥蓝体内硫苷含量。
Glucosinolates（GSs）compositions and contents were analyzed in Chinese kale by foliar spray of the single and combined methionine（Met）and methyl jasmonate（ MeJA）. The aim of paper was to improve quality of Chinese kale by cultivation regulation. The results showed that Chinese kale in all treatments contained 8 glucosinolates. Met didn＇t change the total and individual glucosinolate contents of Chinese kale. The total glucosinolates, indolyl glucosinolates, glucobrassicin and neoglucobrassicin contents were increased by MeJA and Met ＋ MeJA significantly. The above mentioned contents of MeJA treatment were 2.55, 16.59, 11.85 and 86.37 times respectively as compared to control （CK）. Meanwhile aliphatic glucosinolates, sinigrin, glucoraphanin and gluconapin contents were decreased by MeJA and Met ＋ MeJA signifi- cantly. Compared to CK, the contents of MeJA treatment decreased by 32.53 %, 29.79 % ,46.71% and 33.31% respec- tively. The contents of Met ＋ MeJA treatment decreased by 37.04%, 37.58% ,46.44% and 39.36% respectively as compared to CK. It showed that methyl jasmonate could change glucosinolates contents of Chinese kale significantly.
