  • Title: Cadmium accumulation retard activity of functional components of photo assimilation and growth of rice cultivars amended with vermicompost.
    Author: Sebastian A, Prasad MN.
    Journal: Int J Phytoremediation; 2013; 15(10):965-78. PubMed ID: 23819289.
    Abstract:
    Cadmium (Cd) uptake mediated alterations in functional components of photo assimilation during conversion of cow dung and poultry cast to vermicompost were studied in two Indian rice cultivars; MO 16 and MTU 7029. It was found that higher amount of Cd accumulate in plants grown in soil amended with vermicompost which in turn damaged functional components in photo assimilation. Enhancement of root growth was recognized as reason for Cd accumulation. Metabolic alterations noticed among plants were not taken place during application of raw materials used for vermicomposting such as cow dung and poultry cast amendment. Rice varieties accumulated Cd differentially where MTU 7029 accumulated more Cd compare to MO 16. It was also noticed that existence of negative correlation between zinc status of the plant and Cd accumulation.
