为了探索遮光处理与对不同种源一枝蒿种子发芽特性的影响,采用裂区试验,以遮光处理为主区、采集地为副区,研究光照(遮光和不遮光)对不同采集地(沁城野生1、沁城野生2、白石头野生和板房沟栽培)一枝蒿种子发芽特性得。结果表明:不遮光处理一枝蒿种子的发芽率、发芽势和发芽指数均高于遮光处理;栽培一枝蒿种子的发芽率、发芽势和发芽指数均高于野生一枝蒿;就相同采集地,沁城野生第二次采集的一枝蒿种子的发芽率、发芽势和发芽指数低于第一次采集。综上所述,一枝蒿种子宜浅播,以易透光为最佳。野生一枝蒿种子成熟后期可能种皮硬实,影响发芽。
In order to explore the effect of shading treatment and the germination characteristics of Artemisia selengensis seeds from different provenances, the split zone experiment was used to investigate the effects of light (shaded and non-shaded) Wild 1, wild 2 Qincheng, white stone wild and planted Fang Fanggou) Artemisia annua seed germination characteristics have. The results showed that the germination rate, germination energy and germination index of Artemisia selengensis were higher than those of shading without shading. The germination rate, germination energy and germination index of Artemisia selengensis were higher than that of Artemisia annua. City second wild collected Artemisia annua seed germination rate, germination potential and germination index lower than the first acquisition. In summary, an Artemisia seeds should be shallow sowing, easy to light as the best. Wild Artemisia annua seed maturity may be hard seed coat, affecting germination.
