摘　　要：钙作为第二信使在植物信号转导中的作用一直是植物生理学、细胞生物学和发育生物学研究的热点。近年已有不少综述和专著从不同角度对此作了详细评论［1～5］。虽然这些文章中只有部分内容涉及本文的主题———钙在植物受精中的作用，但是它们所论述的关于钙信使系统在植物...The fertilization process in flowering plants in a broad sense includes a progamic phase preceding the phase of double fertilization. To our present knowledge, calcium as a second messenger in the signal transduction plays important roles in all the links of this process. The present review attempts to highlight the recent advances in this research field, including: calcium in relation to in vitro pollen tube growth (distribution of calcium in pollen tube tip; regulation of pollen tube growth by calcium; calcium oscillation in pollen tube); distribution of calcium in pistil and its relation to in vivo pollen tube growth (calcium in relation to pollen_pistil recognition; pollen tube growth in pistil; pollen tube entry into embryo sac and the discharge and transportation of sperms); and calcium in relation to sperm_egg fusion and egg cell activation. In conclusion the author summarizes into several main view points, and gives recommendation for further researches on this topic.
