Detailed Introduction to the Functions and Roles of Rice Leaves
The rice leaf is composed of two main parts: the leaf blade and the leaf sheath, in addition to accessory organs such as the auricle and ligule. The junction where the leaf sheath connects to the stem is called the leaf node. The junction where the leaf sheath connects to the leaf blade is called the leaf collar. When the seed germinates, the first thing to grow out is the coleoptile that protects the young shoot as it emerges, also called the sheath leaf. The sheath leaf differs from other leaves in that it is white and shaped like a cylinder. The second leaf has only a leaf sheath and no leaf blade, and is called an incomplete leaf. Leaves beginning from the third node have both a leaf sheath and a leaf blade, and are called complete leaves. Counting the number of leaves of a variety
