The effects of heavy metal on growth and mitochondrial changes in the Cajanus cajan

Abstract

This study was carried out to determine the effects of heavy metal (Pb and Cd) on growth, relative growth index, tolerance index and ultrastructural alterations of mitochondria in pigeonpea cultivars. The results showed that enhanced concentrations of Pb and Cd decreased the growth, relative growth index, tolerance index of pigeonpea cultivars. Further the ultrastructural studies revealed alterations in the mitochondrial structures in both the cultivars in response to heavy metals.
