摘要
[目的]确定有效破除紫云英种子休眠的方法。[方法]采用机械破除、酸蚀和开水烫种方法处理紫云英种子,研究不同处理方法对紫云英种子发芽势和发芽率的影响。[结果]砂纸打磨处理的种子发芽势和发芽率最高,分别为75%和94%;采用36%浓度的盐酸处理9min,种子发芽势和发芽率分别为25%和52%;29%浓度的双氧水浸种和开水烫种处理的种子发芽率与对照差异不显著,破除效果均不明显。[结论]采用机械摩擦法破除紫云英种子休眠效果最好。
[Objective] The aim was to make sure the dormancy breaking method of Astragalus sinicus L. seed. [Method] The influences of different treatments including mechanical damage, etching and boiled water on the germination energy and germination rate of Astragalus sinieus L. seed were studied. [Result] The germination energy and germination rate of treatment with sand papering were the highest, 75% and 94%. The germination energy and germination rate of treatment with 36% hydroehloride for nine minutes were 25% and 52%. There were no obvious differences on the germination energy and germination rate among seed soaking with 29% hydrogen peroxide, boiled water and the control. [Conclusion] The best method to break dormancy of Astragalus sinicus L. seed was mechanical damage.
