摘要： 采取植物解剖学与发育形态学相结合,光学显微技术的方法,对纤维亚麻的韧皮纤维形态、结构与分布特征,韧皮纤维细胞个体与群体发育的情况及其与麻株生育期和茎段的关系等方面进行了一系列观测分析。结果表明:亚麻韧皮纤维的群体结构、纤维细胞的形态和超微结构因不同的生育阶段、麻株茎段而异,表现明显的遗传和位置效应;亚麻韧皮纤维细胞发育经历分生形成、伸长增粗、胞壁加厚和发育成熟四个相互联系的阶段;麻株韧皮纤维细胞群体发育具有与麻株生长的协同性,发育进程的阶段性。

Abstract: Methods of plant anatomy and developing morphology and technique of optical mi-croscopy were used to observe the morphology, structure and distribution character of bast fiber in fiber-used flax in the study. The development of the individual and collective of bast fiber cells, the relationship between this development and flax-plant and stem part of flax were analysized. The optical microscopical pictures of the development of flax fiber were also taken.The results showed that the collective structure of flax bast fiber,the morphology and super-micro structure of fiber cells were different dued to the difference of developing stages and stem parts, and it showed significant genetic and part effectiveness. The development of flax bast fiber cell underwent four continuous interrelative stages,i.e. ,meristematy formation,elongation,thick-ening of cell wall and maturation. The collective development of bast fiber cells in flax-plant were coordinationally. The process of the development was periodically.

Key words: Flax, Morphology and structure, Development of bast fiber
