摘  要：
[目的]为狼尾草在园林中更好地应用提供理论依据。[方法]以采自崂山的狼尾草种子为材料,研究水分、温度、光照、基质及覆土深度对其种子萌发的影响。[结果]供试狼尾草种子的千粒重为2.34 g;18 h后吸水率达到最大,为45.6%;随着温度的升高,狼尾草种子的发芽势、发芽率和发芽指数呈上升趋势,光照对其萌发的影响不大;草炭+珍珠岩(1∶1)最利于种子萌发,出苗率达70.0%;随着覆土深度的增加,出苗率呈先升后降的趋势,覆土深度为5 mm时,出苗率最高,达76.7%。[结论]狼尾草种子萌发的最适温度为30℃,草炭+珍珠岩(1∶1)为最佳基质,播种以浅埋为好。

摘  要：
[Objective] The study aimed to supply theoretical foundation for applying Pennisetum alopecuroides in gardens better.[Method] With P.alopecuroides seeds collected from Laoshan Mountain as materials,the influences of moisture,temperature,illumination,substrate and covering depth on their germination were studied.[Result] The 1 000-seed weight of tested P. alopecuroides seeds was 2.34 g,their water absorption rate reached the maximum(45.6%) after 18 h.As the temperature ascended,the germination potential,rate and index of P.alopecuroides seeds showed increasing trend and the influence of illumination on their germination was little.The substrate peat + perlite(1∶1) was most favorable for the germination of P.alopecuroides seeds with seedling emergence rate reaching 70.0%.As the covering depth increased,the seedling emergence rate showed the trend of first increasing and then decreasing.When the covering depth was 5 mm,the seedling emergence rate was highest,being 76.7%.[Conclusion] For the germination of P.alopecuroides seeds,the optimum temperature and substrate were 30 ℃ and peat+perlite(1∶1),and shallow covering was better for sowing.
