不同处理方法对威灵仙种子萌发的影响

Influence of different treatment on the germination of Weilingxian seed

目的:以野生威灵仙种子为研究对象,寻找适于威灵仙种子萌发的条件。方法:考察不同试剂和贮藏条件对威灵仙种子发芽率和发芽势的影响。结果:低温贮藏下种子的发芽率和发芽势都显著高于室温贮藏;赤霉素、硝酸钾、多菌灵、萘乙酸处理后,种子发芽率较对照均有提高;浓硫酸处理组没有发芽。结论:低温贮藏条件下的种子经赤霉素处理后发芽时间早,周期短,高峰期集中,是比较适合威灵仙种子萌发的处理方法。

Objective:To study the suitable condition for Weilingxian seed germination using wild Weilingxian seed as the research object. Method:The influences of different reagents and storage conditions on Weilingxian seed germination rate and germination vigor were investigated. Result:The germination rate and germination vigor of seed stored in low temperature were significantly higher than that in room temperature. After treated by gibberellin, kalium nitricum, carbendazol and naphthalene acetic acid, the seed germination rates were increased compared with the control. But the seed treated by concentrated oil of vitriol did not sprout. Conclusion:After the seed stored in low temperature was treated by gibberellin, an early germination with short cycle and concentrated crest-time is found in the study which indicates that the processing method is suitable for Weilingxian seed germination.
