| 摘 要： | 利用排除法和引入昆虫的方法相结合,研究越南篦齿苏铁(Cycas elongata)的传粉媒介.结果表明,越南篦齿苏铁靠风媒传粉和虫媒传粉的雌株结实率分别55.3%和57.2%,自然传粉的结实率为63.5%,说明风和象鼻虫都是越南篦齿苏铁的有效传粉媒介.越南篦齿苏铁散粉高峰在白天,夜间散粉很少,在3.0 m以内风传花粉的密度较高,3.0 m之外的密度急剧下降.可见,风媒和虫媒都是越南篦齿苏铁的有效传粉途径,与泽米铁类植物为专一寄主性昆虫传粉的结论不一致. |

| Abstract: | The pollination vectors of Cycas elongata were studied using exclusive method and introduction insects.The results showed that the seed setting were 55.3% and 57.2% by wind and insect as pollination vector,respectively,which were lower than that under natural pollination(63.5%).The pollinating peak of C.elongata was at the day,and little in the dark.The pollen grains by wind were more within 3 m from the male plant,and decreased markedly over 3 m.It was conclude that wind and weevils were effective pollinat... |
