摘  要：
通过盆栽试验研究了叶面喷施氨基酸对菜心产量和品质的影响。结果表明,喷施200mg/kg甘氨酸和丙氨酸均能提高菜心产量;喷施氨基酸能够显著提高可溶性糖含量,以200mg/kg甘氨酸效果最佳;喷施氨基酸对菜心叶片叶绿素无明显影响,维生素C含量有所降低;喷施甘氨酸能显著降低菜心硝酸盐和草酸含量,最高降低幅度分别为85.03%和70.19%,而喷施丙氨酸硝酸盐含量降低幅度较小,草酸含量显著增加;同时,喷施氨基酸均能够显著提高硝酸还原酶(NR)和谷氨酸脱氢酶(GDH)活性,而且甘氨酸处理效果优于丙氨酸。说明喷施氨基酸,尤其是喷施甘氨酸有利于提高菜心产量,改善品质。

摘  要：
A pot experiment was conducted to investigate the effects of foliar application of different content of glycin and alanine on yield and quality of flowering Chinese cabbage.Five treatments were applied:no fertilizer(CK),foliar application of 200 mg/kg glycin(Gly2),500 mg/kg glycin(Gly5),200 mg/kg alanine(Ala2)and 500 mg/kg alanine(Ala5).Results showed that foliar application of 200 mg/kg glycin and alaninecould improve yield of flowering Chinese cabbage.The content of soluble sugar was increased significantly when amino acid addition with effect of Gly2 was the best.However,no effect was found of amino acid on chlorophyll,VC decreased when foliar application of amino acid.Treatments with glycin could reduce the content of nitrate and oxalic acid significantly,decreased by 85.03%and 70.19%,respectively.While thecontent of nitrate with alanine treatments was reduced fewer and the content of oxalic acid increased significantly.The NR and GDH were increased significantly by foliar application of amino acid,but the effects of glycin was better than those of alanine.It was suggested that foliar application of amino acid,especially glycin,could improved the yield and quality of flowering Chinese cabbage.
