多花梾木种子发芽特性研究

Seed Germination Characteristics of Cornus florida

[目的]研究多花梾木种子的发芽特性。[方法]采用正交试验设计,研究在不同温度、不同酸蚀时间、不同GA3浸种浓度对种子发芽率的影响。[结果]温度对种子发芽影响较明显,在5℃低温处理下时长100 d发芽率最好,达72%。[结论]低温处理在一定条件下能提高多花梾木种子的萌发能力。

[Objective]Seed germination characteristic of Cornus florida was studied.[Method]Seed germination characteristics of ornusflorida under different temperatures,different acid etching time and GA3 concentration was investigated by orthogonal experiment design.[Result]The temperature has an obvious effect on seed germination.The germination rate can reach 72％ when the seeds were stored for 100 days under 5 ℃ low temperature treatment.[Conclusion]Low temperature treatment can enhance the germination ability of seeds under certain conditions.
