摘要
作者在对白刺属的胚胎学进行了详细研究的基础上，比较了该属与蒺藜科内Ｆａｇｏｎｉａ，ｓｅｅｔｚｅｎｉａ，ｚｙｇｏｐｈｙｌｌｕｍ，ｐｅｇａｍｕｍ，Ｂａｌａｎｉｔｅｓ等属的胚胎学特征，发现白刺属在花药壁的发育、小孢子四分体排列，雌蕊的结构、胚珠的数目、珠心的发育、珠被绒毡层有无、珠孔的构成、大孢子孢原和大孢子母细胞的数目、胚柄的发育、多胚现象、果实的发育和类型等方面存在明显的差异．结果表明胚胎学特征支持将白刺属独立为白刺科的观点．文中对蔟藜科胚胎学及系统学研究作了结论．
On the basis of the detailed studiy on the embryology in Nitraria sibirica Pall., the authors compared the characters of this genus with Those of the other genera in Zygophyllaceae,i.c.Fagonia, Scetzenia. Zygophyllum, Peganum, Balanites, and ered a distinct difference on the author wall development. microspere tetrads, gynoecium,ovule number in each locule, nucellus development,the presence or absence of the intemont tapetum formation of micropyle, endothelium,number of archespore and megaspore mother cell, suspensor developmnet, polyembryony,fruit dcvclopmnet, etc. The conclusion supports that the Nirtfaria should be separated from Zygophyllaccac, and set up a family Nitrariaceac.
