植物体内硝酸还原酶(NR) 和亚硝酸还原酶(NiR)活性的测定一般是根据底物的减少来衡量的.本方法则是根据酶促反应的最终产物(氨)的释放来衡量的,能较真实地反映酶活性的大小.测定时,可通过外源基质的选择来衡量硝酸还原酶或亚硝酸还原酶的活性.
Determination of nitrate reductase (NR) and nitrite reductase (NiR) activity in plants is generally based on the reduction of the substrate The method is based on the release of the final product of the enzymatic reaction (ammonia) Can more accurately reflect the size of enzyme activity determination can be measured by exogenous matrix nitrate reductase or nitrite reductase activity.
