摘　　要：在沈阳地区引种棋盘山野生罂粟和剪秋罗2种地被植物的种子,分别用不同的培养温度、不同的浸种温度和不同浓度的3种药剂(KH_(2)PO_(4)、GA3和6-BA)浸种处理,研究了种子的发芽率、发芽势和发芽指数,结果表明:40℃清水浸种可促进野罂粟和剪秋罗种子的萌发,在变温(25℃/15℃)的条件下野罂粟、剪秋罗的发芽情况最好,用200 mg·L^(-1) GA3浸种处理或100 mg·L^(-1)6-BA浸种处理,野罂粟种子萌发效果最好。The seeds of two ground cover plants(Papaver nudicaule and Lychnis fulgens)from Qipan Mountain were introduced in Shenyang Region,different cultivation temperature,different soaking temperature and different concentration of three chemicals(KH_(2)PO_(4),GA3 and 6-BA)were used to conduct seed soaking treatment.The germination rate,germination potential&germination index of the seeds were studied.Result shows that:40℃water soaking can promote the germination of Papaver nudicaule and Lychnis fulgens seeds,under the condition of changing temperature(25℃/15℃),the germination situation of Papaver nudicaule and Lychnis fulgens is optimal.Under the conditions of 200 mg·L^(-1) GA3 seed soaking treatment or 100 mg·L^(-1)6-BA seed soaking treatment,the germination effect of Papaver nudicaule seeds is optimal.
