甜菜在营养生长阶段,就已形成肥大直根。此现象除因块根具有三生结构外,与生育期中叶丛的繁茂亦有关系。特别是与根出叶的关系更为密切。本文报导了甜菜叶器官的解剖结构及发展与分化的规律,为深入开展甜菜各方面的研究工作从植物解剖学角度提供理论依据。 Beet nutrition in the growth stage, it has formed hypertrophy root. In addition to the root cause of this phenomenon, there is a triadic structure, which is also related to the lush foliage in the growth period. In particular, the relationship with the root out more closely. This paper reports the anatomical structure, development and differentiation of beet leaf organ, and provides a theoretical basis for the further study of sugar beet from all aspects of plant anatomy.
