习惯上认为玉米子粒品质是指玉米子粒的蛋白质和赖氨酸含量。这是很不全面的。实际上玉米子粒的主要成分胚和胚乳是存在变异的,因此完整的玉米子粒的品质概念,应按照子粒中各种化合物的组成变化和子粒的用途,分为几种不同的品质类型. It is customary to assume that corn quality refers to corn protein and lysine content. This is very incomplete. In fact, the main components of the maize grain embryo and endosperm there is variation, so the concept of complete maize grain quality should be based on the composition of the various compounds in the grain changes and the use of grain, divided into several different types of quality.
