- 摘要:
- 以草原老鹳草和毛蕊老鹳草为试材，采用不同种子处理方法、不同的萌发温度条件，测定2种老鹳草种子的发芽率、发芽势，研究老鹳草种子萌发特性，以期为老鹳草属植物的选育、繁殖提供参考。结果表明：不同老鹳草属种子在相同处理条件下的萌发率不同。2种老鹳草属种子萌发要求的最佳温度也不同。草原老鹳草种子发芽率最高是经砂纸摩擦处理组，为88.3%，发芽势为88.3%，最佳萌发温度为20 ℃。毛蕊老鹳草种子发芽率最高的是砂纸摩擦处理组，为86.6%，发芽势为86.6%，最佳萌发温度为25 ℃。
- Abstract:
- Geranium pratense and Geranium platyanthum were used as test materials,under different seed treatments and different temperature conditions，the germination rate and germination potential of two kinds of Geranium seeds were determined，and the germination characteristics of Geranium were studied in order to provide reference for breeding and reproduction of the genus Geranium.The results showed that different Geraniums had various germination rates at the same condition.The best temperatures of germination were different between these two Geraniums.The highest germination rate of Geranium pratense seeds was up to 88.3% and the highest germination potential was up to 88.3% at 20 ℃，when the seeds were scraped with sandpaper.Correspondingly，Geranium platyanthum seeds,the highest germination rate up to 86.6% and the highest germination potential was up to 86.6% at 25 ℃，when the seeds were scraped with sandpaper.
