稀土Nd3+和牛蒡低聚果糖对当归种子萌发的影响

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。

Effect of Nd3+ and Burdock oligosaccharide on the Germination Power of Angelica sinensis Seeds

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 80 mg/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 1 g/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.
