摘　　要：对辽宁地区耐寒杜鹃花资源进行了详细的调查。结果:①辽宁野生杜鹃花共有6个种和1个变型,6个种分别是:牛皮杜鹃(R.aureum)、无名杜鹃、大字杜鹃(R.schilippenbachii)、照白杜鹃(R.micranthum)、兴安杜鹃(R.dauricum)、迎红杜鹃(R.mucronulatum);1个变型是缘毛迎红杜鹃(R.mucronulatum f.ciliatum)。广泛分布在辽宁地区的山地林中或山顶。由于分布区大多离居住区较远,加上相关部门的有效保护,野生植株生长状况良好,种群数量稳定。②辽宁地区自然条件下栽培的露地杜鹃花有6种,有观赏价值的变型2个。可依花期分为早花型(迎红杜鹃、毛叶迎红杜鹃、兴安杜鹃),花期4～5月;中花型(大字杜鹃、淀川杜鹃R.yedoense、黄杨杜鹃R.yedoense‘huangyang’、红枫杜鹃Rhododenron‘hongfeng’),花期5～6月;晚花型(照白杜鹃),花期6～7月。The resource of hardy rhododendron in Liaoning was investigated.The results show that there are six species（R.aureum,name-undetermined rhododendron,R.schilippenbachii,R.micranthum,R.dauricum and R.mucronulatum） and one variant（R.mucronulatum f.ciliatum） of wild rhododendron in Liaoning.They are widely distributed in mountainous forest areas or peaks.Because they grow far from residential areas and the government has taken effective measures to protect them,these wild plants grow in good condition with steady population.At present,there are six species and two variants of rhododendron being cultivated under natural conditions in Liaoning.According to florescence,they can be divided into early-flowering-type（R.dauricum,R.mucronulatum） with flowering stage of 4～5 months,middle-flowering-type（R.schilippenbachii,R.micranthum,Hongfeng Rhododendron,R.yedoense and Huangyang R.yedoense） with flowering stage of 5～6 months and later-flowering-type（R.micranthum） with flowering stage of 6～7 months.
