Abstract:This paper reviews studies on importance of clonal plants at community\|level, habitat preference and competitive relations of clonal plants. The relation of plant species diversity to importance of clonal plants was concerned based on competitive relations and habitat conditions. The hierarchical (genet\|ramet system\|ramet) organization of clonal plants offers a variety of strategies in life history, resource use and space occupation that are specific to clonality. We present examples for clonal traits an...
