植物可以利用的两种结合态氮NO_3~-和NH_4~+对植物的生长和代谢有不同的效应。硝酸还原酶是植物体内硝酸盐同化过程中的限速酶,在植物氮代谢中起着十分重要的作用。将硝酸还原酶活性作为作物栽培、育种指标已有许多研究,由于茶树体内多酚类物质对硝酸还原酶的抑制作用给离体测定其活性带来困难,作者对常规硝酸还原酶活性测定方法进行修改,用成功的改进方法试着对茶树硝酸还
The two kinds of bound nitrogen, NO_3 ~ - and NH_4 ~, which plants can utilize have different effects on plant growth and metabolism. Nitrate reductase is the rate-limiting enzyme in nitrate assimilation in plants, and plays a very important role in plant nitrogen metabolism. Nitrate reductase activity as a crop cultivation, breeding indicators have been many studies, as polyphenols in tea body inhibition of nitrate reductase activity in vitro determination difficult, the authors of conventional nitrate reductase activity determination method for Modify, try the tea tree with nitric acid with the successful method of improvement
