摘　　要：【目的】观察不同浸种处理对阳春砂种子发芽的影响，寻找提高砂仁种子发芽力的适宜浸种方法。【方法】设置9个浸种处理实验组，对照组无浸种，处理1组浸泡于15mg／L萘乙酸8h，处理2组浸泡于100mg／L赤霉素30h，处理3～8组分别浸泡于清水8、20、30、40、45、50h，每期播种量为100粒，按株行距4cm×4cm，采用室外盆播方式播种。【结果】萘乙酸对种子发芽起明显抑制作用，并使种子推迟出苗。赤霉素浸种可明显提高种子发芽力，并诱导砂仁种子提前萌发。8h清水浸种对砂仁种子发芽无显效，20～50h浸种则发芽力有不同程度的提高，尤以30～50h为佳。【结论】赤霉素及清水浸种处理可明显提高砂仁种子的发芽力，方法既简单实用又经济实惠，可广泛推广应用于砂仁的播种育苗生产实践中。Objective To optimize the soaking treatment method for increasing the villosum Lour. （AVL） seeds. Methods Nine groups were set up： the control germination of Amomum group （ without soaking treatment）, treatment group 1 （soaking AVL seeds with naphthylacetic acid 15 mg/mL for 8 hours）, treatment group 2 （ soaking with gibberellin 100 mg/L for 30 hours） and treatment groups 3 - 8 （ soaking with clean water for 8, 20, 30, 40, 45 and 50 hours respectively）. The sowing amount was 100 grains in each group for each time, and the seeds were planted in the outdoor pot at a planting space of 4cm × 4cm. Results Naphthylacetic acid had an obvious inhibition on the germination of AVL seeds and delayed the shooting. Gibberellin promoted the germination and shooting of the seeds. Soaking with clean water for 8 hours had no obvious effect on the seed germination, hut soaking for 20 -50 hours increased the seed germination to various degrees, in particular soaking for 30 -50 hours. Conclusion Soaking with gibberellin or clean water can increase the germination of AVL seeds. This method is simple and practical and economic, and is worth of extensively applying in the sowing and breeding of AVL seeds.
