摘　　要：目的:研究百蕊草形态特征和生长发育特性。方法:通过野外定点观察、盆栽实验和室内实验相结合的方法,进行百蕊草形态特征和生长发育特性的研究。结果与结论:百蕊草为多年生半寄生草本,必需依赖于寄主才能完成其生活史。主侧根发达,但根毛退化,根上有吸器夹附在寄主植物根上而生长。茎纤细淡绿色,宿根苗基部簇生,基部以上疏分枝,斜生;实生苗单茎直立生长。宿根苗花期3 4月,实生苗花期4 5月,宿根苗果期3 5月,实生苗果期5 6月。百蕊草野生分布于靠近水体或水源充分的荒草坡、田埂杂草丛中。喜温暖湿润气候,喜光照,忌干旱。种子有休眠期特性,物候期可分为出苗期、分枝期、花期、结果期、枯萎期。Objective:To study the biological and growth characteristics of Thesium chinense.Method:The wild population was observed in certain sites,pot and indoor experiments were applied for cultivated plant.Result and Conclusion:T.chinense is an obligate root hemiparasite and perennial herb,stem and leaf were green,there were haustoriums on its root,can only achieve its whole life process when parasitized to host.T.chinense grows mostly in the humid wasteland and herbaceous community where water is generally abundant.T.chinense likes light,warm climate and acidic to neuter soil.The seeds of T.chinense have dormancy characteristics.The life history of T.chinense can divide into 5 stages:seedling,ramify,florescence,fructification and withering periods.
