Three ramet clones of Solidago altissima were grown under greenhouse conditions to determine the effects of varying levels of attack by the goldenrod ball gallmaker (Eurosta solidaginis) on biomass allocation, leaf senescence rate and rhizome connections among ramets. The results, examined at both the individual ramet level and the clone level, showed that galled ramets became isolated from their clone through deterioration of rhizome connections. Gall effects were only observed at the ramet level although rhizome connection effects were detected at both the ramet and clone levels. The goldenrod ball gallmaker may therefore have little evolutionary impact on large clones but could appreciably affect newly established clones.
在温室条件下种植了三个多花高茎一枝黄花的分株克隆，以确定不同程度的一枝黄花球瘿蜂（Eurosta solidaginis）侵害对生物量分配、叶片衰老速率以及分株间根状茎连接的影响。在个体分株水平和克隆水平上进行检验的结果表明，受瘿害的分株通过根状茎连接的退化而与它们的克隆体隔离开来。尽管在分株和克隆水平上都检测到了根状茎连接效应，但瘿害效应仅在分株水平上被观察到。因此，一枝黄花球瘿蜂可能对大型克隆体几乎没有进化影响，但会显著影响新建立的克隆体。
