采用实地观测的方法，对南充市金城山三个不同生境中柔毛淫羊藿的开花物候特征及其生殖特性进行了研究.结果表明：柔毛淫羊藿花期为3月上旬至4月上旬，其种群、个体、花序和单花的花期分别历时30~41、22~34、9~18和4~8 d.三个生境中柔毛淫羊藿种群的开花物候进程基本相同，均呈单峰集中开花式样，因而能够吸引更多的传粉者访问而达到生殖成功.开花物候指数与坐果数之间的相关分析结果表明，坐果数与始花日期存在显著的负相关关系，与花期持续时间和开花数均呈极显著的正相关关系.揭示了药用植物柔毛淫羊藿的开花物候特征与生殖特性.

This paper studied phenological characteristics of Epimedium pubescens in three different habitats and its effected on reproductive success by using field observations.The results showed that the flowering span of the popu-lation,individual,inflorescence and single flowering were approximately 22-34,31-41,9-18 and 4-8 d,respec-tively.The flowering amplitudes curves of E.pubescens individual plant in three samples were basically identical,and showed a single peak concentration blossom style.The correlation analysis among the first flowering date,duration, flower number and fruit number showed that there was negative correlation between fruit number and first flowering date and a positive correlation to flower number and duration.
