| 摘 要： | 对加拿大一枝黄花、黄莺、一枝黄花3种一枝黄花属植物进行了种子形态学、微形态学观察和发芽率试验,结果显示,根据种子外观和大小,可以区分这3种一枝黄花属植物的种子,一枝黄花的种子大小明显大于黄莺和加拿大一枝黄花,黄莺与加拿大一枝黄花相比,种子更小,种棱不明显,附属毛更为密集;一枝黄花种子内含物饱满度丰富,发芽率较高,加拿大一枝黄花次之,黄莺种子无内含物,发芽率极低。扫描电镜下可以看出黄莺种皮表面被有密麻小刺,明显多于加拿大一枝黄花,且小刺长短及类型均不相同,一枝黄花则表面较光滑,无附属物。 |

| Abstract: | Morphological,micromorphological observation and germination test on seed of Solidago canadensis,S.goldenwings and S.decurrens showed that seed size of S.decurens was the biggest,then that of S.canadensis,the smallest was that of S.goldenwings,without evident rib of seed coat and with denser pubescent.S.decurrens had fuller seed and higher germination rate compared with S.canadensis,while S.goldenwings had seed lack contents.Surface of S.goldenwings was more spiniferous than that of S.canadensis,while that of S.decurrens was smooth. |
| Keywords: | Solidago canadensis S goldenwings S decurrens seed morphology |
