摘    要:采用相同营养液进行水培的方式研究了7种叶菜硝酸盐含量积累及其原因。结果表明,7种叶菜叶片硝酸盐含量差异较大,这种差异主要是由于不同叶菜叶片内硝酸还原酶活性的差异、根系对硝酸盐的吸收速率以及叶片中硝酸盐的代谢库和贮存库的不同造成的;不同叶菜叶片硝酸盐含量与内在硝酸还原酶活性和代谢库的大小有明显的负相关,与贮存库和吸收速率有明显的正相关。

关 键 词:叶菜  硝酸盐  硝酸还原酶活性  代谢库  Km  Vmax

Abstract:The nitrate content difference and the reson among seven kinds of leafy vegetable were studyed in hydroponical experimen.The results showed that a large difference of nitrate content among seven kinds of leafy vegetable’s leaf;It was the main reason of nitrate content difference among seven kinds of leafy vegetable that the NRase activity of leaf,absorption rate of nitrate, Metabolic pool and storage pool of leaf were difference;There was a significant negative line correlation between nitrate content and NRase activit,Metabolic pool;There was a significant positive correlation between nitrate content and storage pool,absorption rate.
Keywords:Km  Vmax
