摘　　要：以青藏高原高寒草甸具有花色多态性的钝裂银莲花为材料，研究其种子形态、种子大小、种子萌发率、发芽势和贮藏时间对种子生活力的影响。结果表明：三种花色钝裂银莲花种子在种子形态、种子大小以及萌发率方面无显著差异；在种子发芽势上白色居群种子与其他两色种子之间有显著差异，可能与白色居群物候期较早有关；种子贮藏时间长度与种子生活力负相关，但是其种子经过长期保藏依旧具有一定种子活力。种子以稳定的形态和大小遗传、较高的萌发率和种子持久的生活力是其对恶劣环境的一种适应。In Qinghai-Tibet plateau alpine meadow Anemone obtusiloba with color polymorphism as materials,seed shape, seed size, seed germination rate, germination energy and storage time on seed viability. The results showed that： three colors Anemone obtusiloba seed was no significant difference in seed shape, seed size and germination rate; there are significant differences between the white population and the other two color seed germination potential on seeds and white populations may phenophase earlier related; the length of seed storage time and negatively correlated with seed viability, but its long-term preservation seed after seed still has some vigor. Seeds in a stable form and size genetic, higher germination rate and seed lasting viability which is one of its adaptation to harsh environments.
