摘要
采用扫描电镜(SEM)对分布于内蒙古不同生境8个样地的冷蒿种皮微形态结构进行的观察结果表明:冷蒿种子在形状、颜色表现出许多相似之处,而不同生境冷蒿种子的大小差异明显;种皮微形态多以纵条纹状肌理的雕纹出现,多有种脐和衣领环退化结构,但在条纹宽窄、粗细、高低、紧致或疏松等结构方面有所差异。
Artemisia frigida from eight samples with different habitats in Inner Mongolia,were observed in detail by scanning electron microscopy （SEM）.The results showed that：the seed of Artemisia frigida in the shape and color exhibited many similarities,but significant differences in seed size; the seed coat micromorphology were mostly vertical stripe sculpture and had hilum and deteriorating structures of collar ring,but in the stripe width、thickness、height、compact or porosity and other structural aspects were different.The results reflected that Artemisia frigida exhibited survival strategy on the morphology structure for adapting to different habitats.
