新陈代谢是生命活动最重要的特征。生物体内的新陈代谢过程是由各种各样的生物化学反应所组成。生物化学反应需要酶参加,酶不仅是代谢过程的调节者,其本身也参加代谢过程。栽培作物的许多重要的农业性状都与酶的活性有一定的关系,栽培条件或品种特性对作物产量和品质的影响,也往往是首先影响酶的活性从而影响代谢过程,最后反映到产量和 Metabolism is the most important feature of life activity. The metabolic processes in living organisms consist of a variety of biochemical reactions. Biochemical reactions require enzyme participation. Enzymes are not only regulators of the metabolic process, they also participate in metabolic processes. Many important agricultural traits of cultivated crops have a certain relationship with the activity of the enzyme. The effects of cultivation conditions or varieties on crop yield and quality often affect the enzyme activity first and then the metabolic process, and finally reflect the yield and
