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

Cultivation Techniques for the Space Red Rice Variety Weihong Jingjing Rice
The only Weihong Jingjing rice in China that has passed space breeding and been approved (approved name: Ganwanxian 33) is a high-quality red rice new variety developed by rice breeding expert researcher Li Yuanxiang together with the Institute of Genetics of the Chinese Academy of Sciences by sending 1000 seeds of the dual-purpose mid-late indica genetic engineering rice "GER-3" aboard a recoverable satellite, selecting mutants after mutagenesis, and then carrying out 3 years of directional breeding. It is also the only red rice variety among China's space rice varieties. After introduction and planting at our base, the plants perform well, show no photoperiod sensitivity or thermosensitivity reactions,
