Abstract:
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.
