本文报道小麦雄性不育三系及杂种一代叶绿体亚显微结构的比较研究.发现不育系83A和保持系83B的片层结构发育不良,排列紊乱,片层之间有肿胀现象;2721恢复系叶绿体的片层系统发育正常,具有典型的结构;杂种小麦(83A×2721)叶绿体的基质片层和基粒类囊体的垛叠更为发达,为杂种优势的发挥提供了亚显微结构的光生物学基础.
This paper reports a comparative study on the sub-microstructure of chloroplasts in three-line and hybrid generations of male sterile wheat. The results showed that the lamellar structures of male sterile line 83A and maintainer line 83B were dysplasia, disordered and swollen between the layers. The chloroplast lamellae system developed normally with a typical structure. The lamellae of the chloroplast in the hybrid wheat (83A × 2721) were more well-developed in the lamellae and provided the sub-microstructure for heterosis development Photobiology Foundation.
