Effects of Cu on Germination and Seedling Growth of Festuca arundinacea L. and Lolium perenne L.
The effect in Cu of different concentrations on germination, seedling growth, and accumulative ability of Cu of Festuca arundinacea L. and Lolium perenne L. was studied by means of soil cultivation experiment. The results showed that germination and seedling growth had negative correlation with the increase in the concentrations of Cu,namely the inhibition strengthened. With an increased in Cu concentration, the content of Cu in plant was enhanced distinctly, and Cu content in root was more than in shoot. Under Cu treatment, there was no distinct difference between germination of two kinds of turfgrass, but the effect on their biomass was different, and the inhibition of Cu treatment to Festuca arundinacea L. was more than Lolium perenne L. The content of Cu in root of Festuca arundinacea L. was less than it in root of Lolium perenne L., but the content of Cu in plant of Festuca arundinacea L. was as much as it in plant of Lolium perenne L.
