本课题是对亚麻纤维的发生、发育规律及不同部位纤维分布的解剖学研究。亚麻纤维细胞是从皮层薄壁组织最内层——长生锥里的输导束鞘内分化出来的,它们成束存在,呈环状分布于皮层中。一个纤维束一般有13～20个单纤维由果胶质紧密粘接在一起。茎的周围有20～40根纤维束组成密度不同的环。纤维束依靠从一个束过渡到另一个束的一些单纤维彼此相互连接,形成坚固完整的纤维网。将纤维层同木质部分离后,可得到完整的带状纤维,即工艺纤维。亚麻纤维形成发育规律分为:纤维细胞形成积累、细胞壁增厚、纤维细胞成熟三个阶段。亚麻茎的中部(20～80节)纤维含量高,质量好,是构成高产优质纤维的主要部分。直径1.0～1.5毫米长麻率最高,质量最优。
This topic is on the occurrence of flax fibers, the development of law and different parts of the fiber anatomy. Flax cells differentiate from the bundle sheath in the innermost layer of the parenchyma of the cortex parenchyma, which are present in bundles and circulate around the cortex. A fiber bundle generally 13 to 20 single fibers by pectin close together. There are 20 to 40 fiber bundles around the stem that make up rings of different densities. Fiber bundles rely on the interconnection of individual filaments that transition from one bundle to another to form a strong and complete web. After separating the fiber layer from the xylem, a complete ribbon of fibers, the process fiber, can be obtained. The formation and development of flax fiber is divided into: the formation of accumulation of fibroblasts, cell wall thickening, fibroblast maturation of three stages. The middle of the flax stems (20 to 80 knots) have high fiber content and good quality, making up the majority of the high-yield, high-quality fiber. 1.0-1.5 mm in diameter, the highest rate of linen, the best quality.
