以紫锥菊的种子为研究对象,采用4℃冷藏处理7 d后37℃温水浸种、硼酸浸种、吲哚乙酸(IAA)浸种、不同的乙醇浓度结合37 ℃温水浸种以及直播等方式对紫锥菊种子的发芽率进行了分析.结果表明,4℃冷藏处理7 d后37℃温水浸种、硼酸浸种、吲哚乙酸浸种均能提高种子的发芽率.其中,IAA(40 mg·L-1)浸种的发芽率最高,达到97.5%;其次是0.1%硼酸浸种、4℃冷藏7 d后37℃温水浸泡12 h,分别达到93.3%、92.7%.在温室直播育苗中,蛭石基质高于泥炭基质的种子发芽率,分别达到89%和76%.综合以上分析可以得出,温室直播育苗宜采用蛭石基质,田间播种前宜选用IAA(40 mg·L-1)浸种24 h.

Selecting the seeds of Echinacea purpurea as the objects, the germination rates were analyzed by soaking in warm water at 37 ℃ after 7 days stored at 4 ℃, soaking in boric acid, soaking in indole acetic acid(IAA), soaking in ethanol of different concentration combined with 37 ℃warm water, and seeding directly. The results show that soaking in warm water at 37 ℃ after 7 days stored at 4 ℃, soaking in boric acid and in indole acetic acid(IAA)can improve the germination rate. The seed germination of soaking in IAA(40 mg·L-1)was the highest(97.5%), followed by soaking in 0.1% boric acid (93.3%), and soaking in warm water at 37 ℃ after 7 days stored at 4 ℃ by 12 h(92.7%), respectively. The seed germination rate of vermiculite substrate(89%)was higher than that of the peat substrate(76%)when seeding directly in the greenhouse. In conclusion, seeding directly in the greenhouse should select the vermiculite, and before sowing in the field, the seeds should be soaked in IAA(40 mg·L-1)for 24 h.
