摘要
植物濒危原因很多 ,其中主要原因是由于繁殖困难造成个体数量减少而面临濒危。本文综述了被子植物胚胎学研究的主要内容及在珍稀濒危植物方面开展的研究工作 ,并讨论了 11种植物有性生殖过程存在的薄弱环节 ,为进一步探讨植物的濒危原因和机制 ,以及制定合理的保护措施提供依据。
There are many causes for plants endangered. One of the major causes is the reduction of their individual population resulting from the difficult reproduction. This paper mainly deals with the study of angiosperm embryology and the research having carried out in rare and endangered plants. It also has a discussion about some weak point existing in the course of sexual reproduction of 11 species, and hence providing a basis for further study of the course and mechanism of endangered plants as well as some rational productive measures.
