嵩草属植物的胚胎学

对嵩草属（ Ｋｏｂｒｅｓｉａ） 植物进行了初步的胚胎学研究。该属植物具假四合花粉（ｐｓｅｕｄｏｍｏｎａｄ） ； 药室内壁在二核花粉时期开始螺旋状加厚， 花药表皮在花粉成熟时形成乳突； 成熟花粉具三细胞。胚珠为倒生型， 具厚珠心和双层珠被， 珠孔由内珠被构成， 珠柄的近基部向珠孔增生形成珠孔塞。胚囊的发育为蓼型， 四分体线形排列， 合点端大孢子发育成八核胚囊。受精后， 胚乳核先于受精卵进行分裂， 胚乳的发育为核型。胚的发育为柳叶菜型灯芯草变型。通过比较， 嵩草属植物大小孢子的发育、胚珠的结构、胚囊的发育、胚乳的发育和胚的发育与莎草科中其它类群一致。所以， 根据胚胎学资料， 嵩草属及其近缘属应保留在莎草科中，不该另立为嵩草科。

The Embryology of the Genus Kobresia(Cyperaceae)

The embryology of Kobresia was studied preliminarily. The development of megaspore and microspore, as well as the structure of ovule, is identical to that of other groups in Cyperaceae. The pollen of the genus is pseudomonad, the embryo sac is of Polygonum type, the endosperm is of nuclear type, and the embryogeny is of the Juncus variation of Onagrad type. These embryological characters are agreeable with those of the Cyperaceae. Therefore, the genus Kobresia and its related genera (Carex, Schoenoxiphium and Uncinia) should be retained in the family Cyperaceae other than raised as a separate family, Kobresiaceae.
