摘要：

研究了 3种来自中国北方林下、草地和碱化草甸匍匐茎型克隆草本植物绢毛匍匐委陵菜 (PotentillareptansL .var.sericophyllaFranch .)、鹅绒委陵菜 (P .anserinaL .)和金戴戴 (Halerpestesruthenica (Jacq .)Qvcz .)对由高光照低养分斑块和低光照高养分斑块组成的资源交互斑块性生境的适应性对策。当生长于高光照低养分条件下分株(HL分株 )与生长于低光照高养分条件下分株 (LH分株 )之间的匍匐茎连接时 ,3种克隆植物HL分株、LH分株以及整个分株对系统 (HL分株 +LH分株 )的生物量均得到显著提高。同时 ,LH分株根冠比显著增加 ,而HL分株根冠比显著下降。这表明 ,当互连分株置于由低光照高养分斑块和高光照低养分斑块组成的异质性环境中时 ,3种植物克隆分株均发生了环境诱导的功能特化。克隆内资源共享以及克隆内不同分株的功能特化有利于整个分株系统对局部丰富资源的获取 ,从而能够缓解资源交互斑块性生境对克隆植物的不利影响
