摘　　要：对不同来源的１４份豆科种质材料在内蒙古干旱半干旱草原区进行了建植评价试验。扁蓿豆和赤峰沙打旺适应范围广，在试验区建植效果最佳，和林沙打旺在暖温型典型草原区建植较好，直立黄芪、胡枝子和牛枝子在荒漠草原区的建植率高于典型草原区，草木榍状黄芪、北美岩黄芪和４个北美杂交苜蓿旱生性差，建植率受播种当年降水条件的严重影响。２个羊柴在自然条件下种子萌发率和幼苗成活率低，建植十分困难。Fourteen legumes(nine Chinese collections/cultivars and five North American cultivars)were evaluated for their establishment in the arid and semi-arid grasslands of Inner Mongolia. Melissitus ruthenicus(MERU)and Astragalus adsurgens(ASAD_3)es-tablished the best stands in Huhhot located in the semi-arid area and in Haiya located in the arid area.Astragalus adsurgens(ASAD_1)in Huhhot and Astragalus adsurgens(ASAD_2),Lespedeza davurica(LEDA)and Lespedeza potaninii(LEPO)in Haiya showed good stand establishment.Growth and establishment of Astragalus melilotoides(ASME)and American cultivars,Hedysarum boreale(9024808),Medicago sativa×M.falcata(Ladak, Ranger,Spredor and Travois)depend on the precipitation of the seeding year.Collections,Hedysarum fruticosum var.laeve(HEFR_1 and HEFR_2)had diffictilty of establishment because of their poor germinations and low growth vigors.
