叶鞘
1.
The numbers of vascular bundle and air chamber for leave-sheath of transgenic rice with BADH cDNA were more than those of Zhong .
转 BADH基因水稻品系叶鞘的维管束数、气腔数目比中 8、开系 7、白珍珠多 ,其外表皮角质层比中 8、开系 7、白珍珠相对较厚 ,其维管束面积与中 8、开系 7、白珍珠相差不大 。
2.
The microstructure of leave-sheath of rice were studied with electronic scanning micro scope.
用扫描电镜对水稻叶鞘表面作了观察，叶鞘表面是由多列纵向排列的片状结构单元构成，每片状结构单元包含长形细胞带、硅化－木栓细胞带、气孔带和瘤状乳突带等4种不同结构区带，并对种和亚种间的异同进行了比较研究。
