| 摘要: |
| 利用体视解剖镜和扫描电子显微镜,对一枝黄花属植物一枝黄花、加拿大一枝黄花和黄莺的花及花粉形态进行观察,比较其差异性。结果表明,一枝黄花同其他两种植物花的形态结构差异明显,而黄莺和加拿大一枝黄花均为头状花序只有数量和大小上的差别; 在花粉形态结构观察中,三者萌发孔的形状类型有差别,一枝黄花和加拿大一枝黄花均为下凹沟底,呈宽而浅的木楔形,而黄莺为下凹沟底深切的裂缝沟。3种一枝黄花属植物花及花粉形态存在显著的解剖学种间差异性,可通过花的解剖结构的观察和比较对3种一枝黄花属植物进行区分。 |

| Abstract: |
| Flower and pollen morphology of Solidago were examined by dissecting microscope and scanning electron microscope. The results indicated that Solidago decurrens presented significant difference comparing with other plants from Solidago. However,there was only difference of magnitude and number in flower morphology between S.canadensis and Solidago spp. Germinal aperture of S.canadensis and S.decurrens presented broad and retuse cuniform. And that of Solidago spp. presented interstitial and retuse groove. There were interspecific anatomical differences in flower and pollen morphology among the three species from Solidago,which could be distinguished by its anatomical structure of flower and pollen. |
