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℃。
Geranium prairie and Mao Rui Geranium as test material, using different seed treatment methods, different germination temperature conditions, the determination of two kinds of geranium seed germination rate, germination potential, ge germination seed germination characteristics, with a view to For Geranium plants breeding, breeding provide a reference. The results showed that the germination rates of different Geranium seeds were different under the same treatment conditions. Two kinds of geranium seed germination requirements of the best temperature is also different. The germination rate of grassland geranium seeds was the highest, which was 88.3% by sandpaper rubbing treatment, the germination potential was 88.3% and the optimum germination temperature was 20 ℃. Mulberry Geranium seed germination rate is the highest sandpaper rubbing treatment group, 86.6%, germination potential was 86.6%, the best germination temperature is 25 ℃.
