| Abstract: | Seeds of Elsholtzia splendens Nakai ex F.Maekawa are incubated in Hoagland media containing copper, iron or /and lead, in order to evaluate toxicity of several metals on plants. It has been discovered that the three ions exhibit capacity of decreasing the germinating rates differently. The seed showed a greater tolerance on copper. In addition, the seedling of the plant could grow better in those containing either copper or iron media than that containing lead. When the contents of copper and iron were fixed, an addition of lead could apparently inhibit the growth of the seedlings. |
