| 摘 要： | 利用解剖镜和扫描电子显微镜对大叶藻花序的形态结构进行了观察。大叶藻花小，单性，无花被，雌、雄花同生于一扁平的肉穗花序上。花的结构简单，雄花仅1枚雄蕊，雄蕊1花药，花药1室、无柄、纵裂；花粉为丝状花粉，无纹饰、萌发孔。雌花仅一心皮，有胚珠1颗，柱头两个；柱头细长，柱头表面及柱头到胚珠处细胞壁表面有大量的丝状突起。大叶藻的花序结构已与沉水生活相适应。 |

| Abstract: | Anatomical and SEM observation of the inflorescence showed that eelgrass was a monoecious plant, the male and female flowers were alternately arranged on the inflorescence. Each anther had one chamber, and the pollen of eelgrass was filamentous, with no exine sculpturing, inaperturate. The carpel contained one ovule and two stigmas, there were filaments on the epidermal cells in front of the carpel. All the characters showed that eelgrass had already adapted to submarine life. |
