%X Serpentine soils are distributed in a small area in Korea, and generally exhibit high contents ofNi, Cr, Fe, Mn, Co and Mg. We investigated the growth of woody plants and herbs in the Andong serpentinearea, Korea. Pinus densiflora and P. rigida growing on serpentine soils have high contents of Fe, Mg, Ni andCo, with contents approximately twice as high as those of non-serpentine plants. Tree species on serpentinesoil also had lower ratios of tree height/DBH than trees in a control area. In greenhouse culture experimentson two bodenvag herb species, Setaria viridis and Cymbopogon tortilis, the biomass of the plants was significantlyaffected by soil type but not by seed origins. After 66 days, the growth of S. viridis and C. tortilis seedlingswas significantly inhibited in serpentine soil, and the dry weight of each species showed significant negativecorrelations with soil heavy metal contents (Ni, Co and Cr). These results suggest that the growth of plants wasinhibited by properties of the serpentine soil, and in particular, their high heavy metal concentration, whichinduced dwarfing in woody plants and reduction of total plant biomass in herbs.
