| 摘 要： | 用石蜡切片法对小盐芥(Thellungiella halophila(C.A.Mey.)O.E.Schulz)的受精作用及胚和胚乳的发育过程进行了解剖学观察,结果显示:花盛开前后,是受精作用的核融合时期;受精前,2个极核融合成次生核;受精作用属有丝分裂前型;胚乳发育为核型;胚发育属柳叶菜型,子叶背倚胚根;成熟种子无胚乳.

| Abstract: | The fertilization and embryo development of Thellungiella hallophila(C.A.Mey.)O.E.Schulz were observed by light microscopy and paraffin sectioning.The results showed that the karyomixis in fertilization occurred around the full blooming stage and two polar nuclei fuse into secondary nuclei before the fertilization took place;the fertilization fell into the category of premitotic syngamy,the endersperm development belonged to karyotype,the embryo development was onagrad types and the cotyledons rested their back on the radicles,and the mature seeds hadn't endersperm. |
