杂交水稻与其三系茎、叶解剖的比较有些区别。杂交水稻茎的节间比其三系表现在表皮下和维管束鞘的厚壁组织,以及它的基本组织、维管束的分化程度都较发达;而其基本组织贮藏的淀粉粒则比其三系少得多,随着茎节的增高,淀粉积累愈来愈少或没有,但其不育系淀粉积累最多,保持系和恢复系的淀粉积累则居于中间状态。旗叶的叶肉细胞层次,细胞和维管束的数目,以及主脉的结构和维管束数,杂交水稻都比其三系发达,这些解剖学特征都能使杂交稻增强光合作用能力,加强代谢运输,促进植株的生长发育,提高抗性,达到高产。
Hybrid rice and its three stems, leaf anatomy is somewhat different. The internodes of hybrid rice stems were more developed than those of the third line in the epidermis and in the vascular bundle sheath, and their basic tissues and vascular bundles were well differentiated. However, However, the accumulations of starch in sterility lines were the most, while the starch accumulation in maintainer lines and restoring lines was in the intermediate state. The number of mesophyll cells, the number of cells and vascular bundles in the flag leaves, and the structure of the main veins and the number of vascular bundles in the hybrids are all higher than those of the three lines. All of these anatomical features can enhance the photosynthetic capacity of hybrid rice and enhance the metabolic transport , Promote plant growth and development, improve resistance, achieve high yield.
