摘 要：
以蒙古蒲公英为试材,通过去雄套袋以及石蜡切片法,对蒙古蒲公英胚胎学进行了研究,为蒲公英无融合生殖研究奠定理论基础。结果表明:蒙古蒲公英去雄套袋后结籽率为68.90%,初步判定蒙古蒲公英为兼性无融合生殖。蒙古蒲公英属于蓼型胚囊发育,四核时期,细胞核大小并不一致。成熟胚囊后,中央细胞和卵细胞发育不同步,卵细胞发育一般早于中央细胞。

摘 要：
Taraxacum mongolicu was used as material.Emasculation bagging experiment and paraffin section methods were taken to study embryology of T.mongolicum,in order to a theoretical foundation for the research of apomixis.The results showed that dandelion seed rate for emasculation bagged was 68.90%,thus facultative apomixis was preliminarily believed in T.mongolicum.T.mongolicum belonged to polygonum type sac.During Four-nucleate embryo sac stage,the nucleus size were different.After the development of mature embryo sac,the development of central cell and egg cell were not synchronized,egg cell development was earlier than central cell generally.
