Humic Acid Decreased Hazardous of Cadmium Toxicity on Lettuce (Lactuca sativa L.)

Humic Acid Decreased Hazardous of Cadmium Toxicity on Lettuce (Lactuca sativa L.)

The binding of Cd to humic acid was studied. The influence of a Cd-humic complex on enzyme activities (superoxide dismutases, peroxidases), availability of Cd, and biomass compared with the behavior of no treatment (control). It was examined through a hydroponics system in lettuce. Treatments were:...

Zusammenfassung:The binding of Cd to humic acid was studied. The influence of a Cd-humic complex on enzyme activities (superoxide dismutases, peroxidases), availability of Cd, and biomass compared with the behavior of no treatment (control). It was examined through a hydroponics system in lettuce. Treatments were: control (no additions), humic acid (0, 100 and 1000 mg·L ), and Cd (0, 2 and 4 mg·L ). Enzyme activities increased significantly with increasing rates of cadmium. A significant increase (P
