Overview

Experiments show zinc reduces cadmium accumulation in rice, suggesting improved food safety in contaminated fields.

Key Points

  • The research aims to understand how iron and zinc affect cadmium transport and accumulation in rice.
  • Conducted pot and hydroponic experiments
  • Applied iron and zinc at the tillering stage
  • Measured cadmium levels in rice foliage and grains
  • Iron-zinc treatment reduced cadmium in rice grains by 66%
  • Decreased labile cadmium fractions in foliage by 67% and 50%
  • Enhanced fibrous root development by increasing root area by 51%
