摘　　要：细胞程序化死亡(PCD)是生物生长发育、细胞分化等条件下细胞主动、有序的死亡过程.某些细胞在适当的时期发生PCD是植物生殖过程顺利进行的保证,它已成为一个新的研究热点.由于裸子植物与被子植物在有性生殖过程中的巨大差异,越来越多的研究者开始关注裸子植物有性生殖过程中的PCD问题.在综述裸子植物有性生殖过程中PCD现象和研究进展的基础上,提出进一步研究的方向和可能的意义.Programmed cell death (PCD) is an active and organized process during the growth and development process and cell differentiation of plants. Certain cells undergoing programmed cell death at a suitable time is necessary for the normal reproduction of plants. PCD has gradually become one of the hot research points of plants. Because there are many differences between the reproduction of gymnosperm and angiosperm, more and more researchers are paying attention to the programmed cell death in sexual reproduction of gymnosperm. Recent researches on PCD in gymnosperm reproduction and the importance of further researches related to this aspect were discussed in this article.
