This research was conducted to test cadmium tolerance by five speices of native herbs for screening cadmium tolerance plant. We examined germination rate, root and shoot growth rate of seedling, fresh biomass of native herbs exposed to cadmium solution for 14 days. Especially, germination rate of Abutilon avicennae and Amaranthus retroflexus was over 90% in all concentration, but germination rate of Aeschynomene indica, Echinochloa crus-galli var. oryzicola and Echinochla crus-galli var. frumentacea began to decrease when they exposed to 15 mgCdSO©þ /L. The higher the Cd concentration, the length of root, shoot grew lower. The fresh biomass of Echinochloa crus-galli var. oryzicola, Echinochla crus-galli var. frumentacea and Amaranthus retro-flexus were not so different from each control, but those of Abutilon avicennae and Aeschynomene indica began to decrese greatly when exposed to 60 mgCdSO©þ /L. EC/sub 50/(Effective Concentration 50%) of Abutilon avicennae, Aeschynomene indica and Amaranthus retroflexus was 44.6¡­77.5 mgCdSO©þ /L for root growth, 38.6¡­114 mgCdSO©þ /L for shoot growth, 60¡­107.5 mgCdSO©þ /L for fresh biomass. Among the native herbs, sensitivity of cadmium ordered as root length > fresh biomass > shoot length. These results indicate that Abutilon avicennae is a tolerant species for cadmium.
