The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.
利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

There remained the generic conditions imposed by natural, as distinct from human law, as integral parts of the human whole: the necessity of destruction to procure alimentary sustenance: the painful character of the ultimate functions of separate existence, the agonies of birth and death: the monotonous menstruation of simian and human females extending from the age of puberty to the menopause: inevitable accidents at sea, in mines and factories: certain very painful maladies and their resultant surgical operations, innate lunacy and congenital criminality, decimating epidemics: catastrophic cataclysms which make terror the basis of human mentality: seismic upheavals the epicentres of which are located in densely populated regions: the fact of vital growth, through convulsions of metamorphosis, from infancy through maturity to decay.
