Abstract
Biosolids can enrich the contents of organic matter and nutrients in soils, consequently improving the growth of plants. In order to enhance the transpiration rate and therefore the upward movement of Cd from the soil to the shoots of a potential hyperaccumulator, rainbow pink (Dianthus chinensis), different amounts of biosolid were applied to potted Cd-contaminated soils, and their effects on the leaf area were assessed. Experimental results show that the dry weight of rainbow pink was not significantly affected by the treatments of Cd and biosolid. However, the leaf area and transpiration rate in the biosolid treatments significantly increased compared with the control. There was also a linear relationship between the leaf area and the transpiration rate.
