Effects of Cd2+ and Zn2+ on Seed Germination and Seedling Growth of Lolium perenne L.
Effects of different heavy metal ions on seed germination and seedling growth of Lolium perenne L.. The effects of two heavy metal ions including Cd2+ and Zn2+ on seed germination and seedling growth of L. perenne were investigated. The results showed that Zn2+,Cd2+ and Zn2++Cd2+ significantly inhibited the seed germination and seedling growth. With the increasing of heavy metal ions concentrations, germination rate and germinability of L. perenne significantly decreased, root length and seedling length were also restrained, the content of chlorophy II decreased significantly, the difference was abvious. The study has theoretical and practical value for further research on germination and growth of L. perenne in heavy-metal-contaminated soil.
