利用石蜡切片扫描电镜观察技术 ,对三个不同产量的小麦品种灌浆后期旗叶叶片进行了超微结构观察 ,结果表明 :( 1 )不同产量小麦旗叶的叶肉细胞之间的细胞间隙及叶肉细胞的分布情况不同 ;( 2 )小麦产量不同 ,旗叶的叶肉细胞内叶绿体的大小、数量、分布状况有明显区别 ;( 3 )不同产量小麦旗叶叶肉细胞内线粒体数量不同
The ultrastructure of flag leaf leaves of three wheat cultivars with different grain yield at the late filling stage was observed by means of paraffin section scanning electron microscopy. The results showed that: (1) the intercellular spaces between the mesophyll cells and the mesophyll cells (2) There were significant differences in the size, number and distribution of chloroplasts in the flag leaf mesophyll cells under different wheat yields; (3) The number of mitochondria in the flag leaf mesophyll cells of different yield wheat was different
