- Abstract
The effects of different densities on cadmium (Cd) accumulation of Cerastium glomeratum were investigated through a pot experiment. The results showed that the root, stem, leaf and shoot biomass of single C. glomeratum decreased with the increase of densities of C. glomeratum seedlings (1, 2, 3, 4 and 5 seedlings in one pot), and the Cd contents in stems, leaves and shoots of C. glomeratum increased. The Cd extraction by whole plant of single C. glomeratum increased when the density was less than 2, and decreased more than that. The Cd extraction by stems, leaves, shoots and whole plant of C. glomeratum in each pot increased with the increase of densities of C. glomeratum seedlings. The maximums of the Cd extraction by stems, leaves, shoots and whole plant of C. glomeratum in each pot were 110.55, 81.65, 192.20 and 572.35 µg/pot, which increased by 367.05% (p < 0.05), 348.63% (p < 0.05), 359.04% (p < 0.05) and 243.59% (p < 0.05), respectively, compared with 1 seedling in one pot. Therefore, highly density could improve phytoremediation efficiency of C. glomeratum in Cd-contaminated soil.
