| 摘 要： | 红松天然种群有许多适应风媒传粉的特点，传粉多集中发生在晴朗天气较多的６月中旬，物候期延迟或雨季提前可导致花粉大量损失，授粉不足。花粉在不同高度上分布有一定差异，在授粉在效高度（２５ｍ左右）花粉密度最大。红松花粉短距离传播效率较低。

| Abstract: | The natural populations of Pinus koraiensis have some anemophily advantages.Pollination often occurs in the middle June at clear days.Howere,the phenological delay or raing season advance may cause a great amount of pullens loses.Pallens allocation varies with the different height in the stand.The highest density appears at the available height (about 25m).Korean pine pollens can be transported in a limited distance. |

| Keywords: | Pinus koraiensis natural population pollination by wind |
