Mineral Elements of Subtropical Tree Seedlings in Response to Elevated Carbon Dioxide and Nitrogen Addition
Mineral elements in plants have been strongly affected by increased atmospheric carbon dioxide (CO(2)) concentrations and nitrogen (N) deposition due to human activities. However, such understanding is largely limited to N and phosphorus in grassland. Using open-top chambers, we examined the concent...

description | Mineral elements in plants have been strongly affected by increased atmospheric carbon dioxide (CO(2)) concentrations and nitrogen (N) deposition due to human activities. However, such understanding is largely limited to N and phosphorus in grassland. Using open-top chambers, we examined the concentrations of potassium (K), calcium (Ca), magnesium (Mg), aluminum (Al), copper (Cu) and manganese (Mn) in the leaves and roots of the seedlings of five subtropical tree species in response to elevated CO(2) (ca. 700 μmol CO(2) mol(-1)) and N addition (100 kg N ha(-1) yr(-1)) from 2005 to 2009. These mineral elements in the roots responded more strongly to elevated CO(2) and N addition than those in the leaves. Elevated CO(2) did not consistently decrease the concentrations of plant mineral elements, with increases in K, Al, Cu and Mn in some tree species. N addition decreased K and had no influence on Cu in the five tree species. Given the shifts in plant mineral elements, Schima superba and Castanopsis hystrix were less responsive to elevated CO(2) and N addition alone, respectively. Our results indicate that plant stoichiometry would be altered by increasing CO(2) and N deposition, and K would likely become a limiting nutrient under increasing N deposition in subtropics. |
