Abstract:Copper (Cu) contamination in paddy fields leads to excessive Cu in rice grains and a low grain yield, posing a serious threat to sustainable agricultural production. We propose the application of seed priming with silver ions (Ag + ) as biostimulants to trigger reactive oxygen species (ROS) production and enhance immune responses, thereby improving rice resistance to Cu stress. The results showed that seed priming with 10 μM Ag + significantly improved rice tolerance to Cu, increased the fresh biomass by 22.1%… Show more
