Abstract: Jatropha curcas root border cells were detached from root tip and cultured by aeroponics to study their biological characteristics and the toxic effect of cadmium on their viability. Most of the cells were elliptical, and a few of them presented bend claval shape. The cells had the highest viability when the
root length was 15 mm, and their pectin methylesterase (PME) activity somewhat decreased with root elongation. Cadmium had obvious toxic effect on the cells. With the increasing concentration of cadmium and the increasing treating time, the viability of the border cells all showed a decreasing trend.
