摘　　要：[目的]促进蓝花棘豆种子的萌发。[方法]选用98%浓硫酸浸泡5 min、机械破皮(砂纸摩擦4 min)、温水浸种(20、40、60、80、100℃浸泡1 min,60、80、100℃分别浸泡1、3、5、7 min)、超声波处理(5、10、20、30、40、50、60 min)蓝花棘豆种子,对其发芽率、发芽势、发芽指数、活力指数进行测定与分析。[结果]98%浓硫酸浸泡、机械破皮、温水浸种均可促进蓝花棘豆种子萌发,其中,当浸种温度为80℃、浸泡时间为5 min时,蓝花棘豆种子发芽率有显著提升,发芽势、发芽指数、活力指数显著高于其他处理,其发芽率达到97%。[结论]该研究为促进蓝花棘豆种子的萌发提供了方法。[Objective]To promote germination of Oxytropis caerulea seeds.[Method]The seeds were soaked in 98%concentrated sulfuric acid for 5 min,mechanically peeled(rubbing with sandpaper for 4 min),soaked in warm water(soaking at 20,40,60,80 and 100℃for 1 min,soaking at 60,80 and 100℃for 1,3,5 and 7 min,respectively),and treated with ultrasonic wave(5,10,20,30,40,50 and 60 min).The germination rate,germination potential,germination index and vigor index of the seeds were determined and analyzed.[Result]The results showed that the seed germination of Oxytropis caerulea could be promoted by soaking in concentrated sulfuric acid,breaking the seed skin and soaking in warm water.After being soaked in water of 80℃for 5 min,the germination rate of Oxytropis caerulea seeds was significantly improved,and the germination trend,germination index and vigor index were significantly higher than those of other treatments.And the highest germination rate can reach 97%.[Conclusion]This study provides a method for promoting the germination of Oxytropis caerulea seeds.
