摘　　要：从形态结构、发芽试验、环境因子和处理方法对美女樱种子生物学特性、萌发条件进行了研究,结果表明:美女樱种子为直立型双子叶无胚乳种子,存在7d的休眠期。15/5℃全黑暗条件下用草炭做基质萌发效果较好。不同处理可提高美女樱种子萌发率,其中以清水浸种3h后用0.1%的HO处理5h效果最好,可高达73.8%。The research was done on biological characteristics and germination conditions of Verbena hybrida seed by morphdogical structure, seed germination test, environment factors and treat methods. The results showed that：The seed was erect, dicotyledonous and no endosperm, which dormancy stage was one week. The germination effect was better than others which was seed in grass peat with 15 to 5 ℃ temperature under the conditions of full darkness. The germination percentage of verbena seeds could be improved with different treatments, the best one was soaking seeds with water last 3 hours, then treat with 0.1% H2O2 for 5 hours, the germination percentage could be up to 73.8%.
