为了研究锦鸡儿种子的休眠机制和解除休眠的最佳条件与方法，采用物理与化学方法对不同种源地的刺叶锦鸡儿与荒漠锦鸡儿进行破除休眠研究。结果表明：种皮厚度是影响刺叶锦鸡儿与荒漠锦鸡儿种子萌发的重要因素。在物理与化学方法中，热水处理、机械处理和浓硫酸处理能有效破除2种锦鸡儿种子种皮的阻碍性功能，显著提高锦鸡儿种子的萌发率与萌发指数。浓硫酸处理萌发率可达100％，热水处理萌发率最高值为96％。热水处理、浓硫酸处理具有操作简单、成本低等优点，是锦鸡儿属植物应用于生产实践中的良好方法。

Seed dormancy breaking methods in Caragana roborovskyi and Caranaga acanthophylla were explored by using physical and chemical methods .The results indicated that seed coat thickness was an important factor influencing the seed ger-mination of Caragana roborovskyi and Caranaga acanthophylla .Among the physical and chemical methods ,hot water treat-ment ,mechanical treatment and sulfuric acid treatment could effectively get rid of the blocking function of the seed coat of Ca-ragana roborovskyi and Caranaga acanthophylla ,and significantly improve the seed germination rate and germination indexes . Hot water treatment and sulfuric acid treatment are good methods ,with the advantages of simple operation and low-cost .
