| 摘 要： | 对木兰科、林仙科、八角科、五味子科的种子进行了详细观察,结果发现,木兰科种子为Endotestal型,且合点区具孔或管的特殊形态.其余三科为Extotestal型.由此说明它们与木兰科的亲缘关系较远,木兰科植物是一个自然的组合.

| Abstract: | The seeds of Magnoliaceae, Winteraceae, 111iciaceae and Schisandra-ceae were observed. The results showed that the seeds of Magnoliaceae are ofendotestal seeds with two special morphological types, i. e. the pore type andthe tube type in the chalazal region and the others are of extotestal seeds.It can be deduced that these three families have loose relationships withMagnol iaceae of which species form a natural group. |
