| 摘 要： | 该文研究了9种野生花卉的千粒重、含水量、种子形态及种子萌发特性。试验结果表明，在设定的温度范围15～25℃内，种子萌发难易度有明显不同。大花剪秋萝（Lychnis fulgens）和狭苞橐吾（Ligularia intermedia）较易萌发，发芽历程短，萌发的最适温度分别为25℃和20℃，发芽率分别达到97．3％和100％；芹叶铁线莲（Clematis aethusifolia）、短尾铁线莲（Clematis brevicaudata）和棉团铁线莲（Clematis hexapetala）发芽历程长，种子始发芽晚，在20℃条件下发芽率均达到最高，分别为88％，84％和57．3％。野罂粟（Papaver nudicaule）、牛扁（Aeonitum barbatumvar puberlum）、草本威灵仙（Veronicastrum sibiricum）和金莲花（Trollius chinensis）发芽率低，在试验条件下种子最高萌发率分别为29％，20％，17％和4．0％。

| Abstract: | The 1000-seeds weight, moisture ,seed morphology and germination characteristics of 9 wild species were investi gated. The results showed that the opportune seed germination temperature of Lychnisfulgens was 25℃ with germination rate 97.3% ,and 20℃ for Ligularia intermedia, Clematis aethusifolis, C. brevicaudata and C. brevicaudata, with germination rate 100% , 88% ,84% and 57.3% , separately. The seeds from Trollius chinensis, Aconitum barbatum var. puberulum, Papaver naudicaule and Veronicastrum sibiricum had lower germination ability with fit germination rate of 29%, 20% , 17% 4. 0% ,respectively, in this study. |
