Effect of humic substances on plant tissue accumulations of reactive oxygen species produced by heavy-metal stress

Research grant

Project Description

Restoring vegetation in an area polluted by heavy metals is an important aspect of soil preservation and forest protection. Most plants wither and die under heavy-metal stress, and so it is important to develop a method to alleviate such stress. In this research, which we target at the utilization of humic substances to restore vegetation in areas polluted by heavy metals, we assess the influence of humic substances built up within plant tissue as a result of heavy metal stress.
