Abstract |
Cadmium (Cd)-contaminated rice is a serious health concern. In the present study, Cd accumulation and stress responses in Oryza sativa L. cv MTU 7029 seedlings were characterized under varying concentrations of plant nutrients in Hoagland media. It has been found that nutrient supplement modulates Cd accumulation and related stress tolerance while efficacy of each nutrient varies. Supplementation of Fe, Mn, N, Ca, and S were found to reduce Cd accumulation in leaf whereas Mn and Fe supply effect was also observed in roots. Analysis of maximum quantum efficiency of photosynthesis indicated that Fe and S supplements confer highest Cd stress tolerance. The present study highlighted the potential of plant nutrients for minimizing Cd accumulation and its toxicity in rice seedlings. |
