| 摘 要： | 目的:研究倒心盾翅藤种子的萌发特性。方法:测定倒心盾翅藤种子的形态、千粒重和含水量等指标,利用不同温度和光照、种子带翅或不带翅、不同成熟度、贮藏等处理对种子进行发芽试验,测定其发芽率、发芽势和发芽指数。结果:倒心盾翅藤种子发芽适温为25～35℃,其中30℃条件发芽率最高,光照或黑暗条件均可。果翅对种子的发芽率无显著影响,但会影响种子发芽速度和整齐度。不成熟种子采集后经过贮藏后熟,可显著提高发芽率。种子在室温条件下贮藏6个月,发芽率仍高达93.68%,但贮藏12个月后发芽率显著下降。结论:倒心盾翅藤种子属于高温萌发型、光中性种子;种子最适贮藏时间不超过1年。

| Abstract: | Objective:To study seed Germination characteristics of Aspidopterys obcordata var.obcordata.Method:The morphological characters,1 000-grains weight and moisture content of A.obcordata var.obcordata seed were observed.And studied different temperature and light,seeds with or without wings,seed maturity and storage on the seed germination.Result:The optimal germination temperature of A.obcordata var.obcordata seeds was 25 ℃ to 35 ℃,and seed germination percentage reached a peak at 30 ℃.Seeds could germinate no matter in light or dark.The fruit wings had no significant effect on seed germination percentage,but it showed significant effects on the germination energy and germination index.The germination percentages of immature seeds were evidently increased after a period of storage and after-ripening.The seed germination ratio was still as high as 93.68% after seeds were storied for 6 months at room temperature,but it dropped significantly after for 12 months.Conclusion:Aspidopterys obcordata var.obcordata seeds belonged to the high-temperature-germinating and non-photoblastic type.The most suitable storing time for the seeds was less than 12 months. |
