摘  要：
对河西走廊15种豆科植物种子的萌发特性、萌发模式进行比较研究。结果表明:锦鸡儿一种在有光条件下的萌发率和萌发速率均显著高于黑暗中的萌发率和萌发速率;柠条锦鸡儿在黑暗下的萌发率和萌发速率均显著高于有光条件的;光、暗对其他物种萌发的影响没有差异。在有光条件下,柠条锦鸡儿、中间锦鸡儿和百脉根的萌发属于投机型;沙冬青、邦卡锦鸡儿、川西锦鸡儿和锦鸡儿一种种子的萌发属于中间型;黄华、苦豆子、苦参、树锦鸡儿、乌拉尔甘草和黄芪的种子萌发属于缓萌型;而甘草一种和苜蓿种子萌发属于低萌型。在黑暗条件下,中间锦鸡儿和百脉根的种子萌发属于投机型;中间型的与光照条件下相同;黄华、苦豆子、苦参和树锦鸡儿的种子萌发属于缓萌型,甘草一种、乌拉尔甘草、黄芪、柠条锦鸡儿和苜蓿的种子萌发属于低萌型。

摘  要：
This paper studied the seed germination characteristics and germination patterns of 15 Leguminous plants from Hexi Corridor area.Results were as follows.In the presence of light,the germination rate of Caraganas ssp.was significantly higher than the germination rate in dark.The germination rate of Caragana korshinskii in dark was significantly higher than that under light.It had no effect on the germination of other species whether light existed.There were four main germination patterns.The first pattern was rapid germination,whose representatives were C.korshinskii,C.intermedia and Lotus corniculatus grown in the presence of light.The second pattern was intermediate germination,whose representatives were C.intermedia,L.corniculatus,Ammopiptanthus mongolicus,C.bongardiana,C.erinacea and Caraganas ssp.grown in dark.The third pattern was slow germination,whose representatives were Thermopsis schischkinii,Sophora alopecuroides,Sophora flavescens,C.arborescen,Glycyrrhiza uralensis and Hedysarum multijugum grown in the presence of light,and T.schischkinii,S.alopecuroides,S.flavescens,C.arborescens grown in dark.The last pattern was low germination,whose representatives were Glycyrrhizas ssp.,Medicago falcate,Glycyrrhizas sp,G.uralensis,H.multijugum,C.korshinskii and M.falcate.
