| 摘 要： | 通过对内蒙古自治区鄂尔多斯高原的茭蒿与其他2种蒿属植物种子萌发特性的对比研究。结果表明,茭蒿种子质量很小,千粒重仅为(0.090 1±0.005 1)g,这种特性有利于其种子的传播;茭蒿种子质量虽然很小,但在相同条件下,与其他植物种子发芽率并没有表现出显著差异,即种子质量的大小没有对茭蒿种子的萌发造成影响。茭蒿在拥有小种子的同时又具有高的种子萌发率,是其对黄土丘陵沟谷的有效适应途径。 |

| Abstract: | The loess hill and gully region of Ordos Plateau was selected as the study area.Seed germinations of Artemisia giraldii,Artemisia sacrorum and Artemisia ordosica were characterized comprehensively and analyzed systematically.The results indicate that the seeds of Artemisia giraldii have extremely light weight,as low as(0.090 1±0.005 1)g per 1 000seeds.This trait allows the species to achieve higher dispersal rate than the others.Furthermore,seed germination rate of Artemisia giraldii remained almost same as the other species with similar traits.This suggests that the light seed weight of Artemisia giraldii was clearly not a disadvantage for the success of seed germination.Instead,it enhances the effective adaptability of Artemisia giraldii to the gully habitat. |
| Keywords: | Ordos Plateau Artemisia giraldii Artemisia sacrorum Artemisia ordosica seed germination |
