This study was conducted to investgate the evaluation of Forsythia koreana Nakai, Chaenomeles speciosa Koidz and Ligustrum obtusifolium Sieb. et Zucc. which were reported to have good phytoremediability of cadmium contained soil. Growth responses of shoot length were found that the decrease of Ligustrum obtusifolium Koidz was 60.10㎝ in control and 11.50㎝ in Cd treatment in Jun 7 and poor growth for Chaenomeles speciosa Koidz in Cd treatment were found. Chlorophyll content was lower 3.36㎎/g in the Cu treatment than 4.85㎎/g of control, and the content of Ligustrum obtusifolium Sieb. et Zucc. was decreased 2.57㎎/g in the Cu treatment than 4.17㎎/g of control. Cadmium led to partial chlorophyll degradation and produced small, white to yellowish colored spots, especially on newly formed leaves. Total nitrogen content was the most low in Ligustrum obtusifolium Sieb. et Zucc. treated with Cd, and Different tendency was shown the change of soluble protein content when their growth period passed unlike the tendency of chlorophyll. The comparison of heavy metal accumulators in the root of plants was as follows; Forsythia koreana Nakai＞Chaenomeles speciosa Koidz＞Ligustrum obtusifolium Sieb. et Zucc., and Ligustrum obtusifolium Sieb. et Zucc.＞Forsythia koreana Nakai＞Chaenomeles speciosa Koidz in the top of plants. The choice of proper plants for bioremediation in different sources of heavy metal pollution seems important. In this regard, Forsythia koreana Nakai and Ligustrum obtusifolium Sieb. et Zucc. which showed higher in Cd accumulation of shoots could be used for phytoremediation and phytostabiliza
