The Influence of Iron Application on the Growth and Cadmium Stress Tolerance of Poplar

There is a complex cadmium (Cd) and iron (Fe) interaction in soil. To explore the influences of Fe application on growth, Cd accumulation, antioxidant capacity poplar under exposure, Populus tremula × P. alba ‘717’ was treated with different concentrations (0 100 μM) (50 150 μM). In addition, root architecture, leaf chlorophyll content, enzyme activity were analyzed. The results showed that high-dose (150 did not change biomass zero-Cd treatment but increased total surface area, net photosynthetic rate, accumulation Cd-stressed poplar. stress, translocation factor (TF) Cd, decreased malondialdehyde (MDA) enhanced SOD activity. That is, could alleviate suppression growth enhance transport to aboveground tissues roots leaves, thus alleviating Cd-induced oxidative stress. This study will provide reference for remediation Cd-contaminated soils using
