摘要：

目的与方法：以发芽率和发芽动态为指标，通过不同温度、不同浓度Nd3+、不同浓度牛蒡低聚果糖处理当归种子，探讨当归种子的萌发特性，为当归引种栽培生产提供技术指标。结果：当归种子萌发的最适温度是20-25℃，不同浓度的Nd3+溶液对当归种子萌发都具有促进作用，Nd3+的最适浓度是80mg/L；牛蒡低聚果糖溶液对当归种子萌发的影响表现为高浓度抑制，低浓度具有促进作用，牛蒡低聚果糖的最适浓度是1g/L。结论：稀土Nd3+和牛蒡低聚果糖均能提高当归种子的发芽率，二者对当归引种栽培生产具有潜在的应用前景。

Abstract:

To solve the problem of the technology of Angelica sinensis in introduction and cultivation. The effects of different temperatures, Nd3+ and Burdock oligosaccharide (BOS) on germination rate were studied. The results showed that the germination rate of Angelica sinensis seeds was highest at 25-28 ℃; different concentration of Nd3+ promoted the germination rate of seed respectively, the optimum concentration of Nd3+ was 80mg/L; the low concentration of BOS promoted the germination rate of seed, but the high concentration of BOS inhibited the germination of seed, the optimum concentration of BOS was 1g/L .We conclude that Nd3+ and BOS can promote the germination rate of Angelica sinensis seeds.Both of Nd3+ and BOS on increasing the germination rate of Angelica sinensis seeds may be applied in introduction and cultivation Angelica sinensis in future.
