主　　题：Nutrient integration patch 

摘      要：Patch contrast,defined as the difference between patches,is among the basic traits of environmental heterogeneity(Kolasa and Pickett 1991;Stuefer 1996).Clonal plants,especially those with long spacers,usually experience certain patches with different nutrient-patch contrasts(de Kroon et al.2005;Stuefer 1996).Clonal integration has been recognized as a basic strategy,by which clonal plants can effectively cope with patchy resources and increase their fitness in such habitats(de Kroon et al.2005;Zhang et al.2007).Glechoma longituba is distributed in a wide range of habitats(Wu and Chen 1974).Thus,it appears to be most likely that *** plants grow in habitats with different nutrient-patch *** that integration is highly dependent on source-sink relationships within a clone(Pitelka and Ashmun 1985),we hypothesize that increased nutrient-patch contrast might enhance clonal integration within a *** test this hypothesis,we conducted a garden experiment,in which *** was subjected to four levels of patch contrast.
