| Abstract: |
| The effects of different concentrations of cadmium on the agronomic traits, microstructure and absorption of some mineral elements of fruiting bodies were studied by adding cadmium(Cd) in the culture medium. The results showed that, with the increase of Cd concentration in the culture medium, agronomic traits, such as the average weight per pileus, per stalk and per fruit body, the average diameter per stalk and per pileus, and so on, increased first and then decreased, indicating that lower concentrations of Cd(<2.5 mg·kg-1) could promote agronomic traits, that higher concentrations of Cd could inhibited agronomic traits, and that Cd could affect yield by influencing agronomic traits. Low concentration of Cd(<2 mg·kg-1) could promote the growth of spores and cystidium, while high concentrations of cadmium(>2 mg·kg-1) had toxic effects on spores and cystidium. Cd in different concentrations could inhibit the absorption of zinc(Zn), but promote the absorption of copper(Cu) and iron(Fe). Low concentration of Cd could inhibit absorption calcium(Ca) and magnesium(Mg), and high concentrations of cadmium could promote absorption of Ca and Mg. |
