Changes in lipid and phospholipid content of cajanus cajan seedlings in response to cadmium toxicity

Seedlings of pigeonpea (Cajanus cajan L. Mill.) grown on treated with different cadmium (Cd) concentrations representing 0, 0.02, 0.04 and 0.06 mM were used in three pigeonpea cultivars, LRG30, LRG41 and ICPL85063 on membrane permeability, lipid and phospholipid contents were studied. The consequent loss of membrane permeability to nonelectrolytes were expressed more in cv.LRG41 and ICPL85063 in response to Cd treatment indicating heavy metal sensitivity of LRG41 and ICPL85063. Decreased lipid and phospholipid contents were more in cv.LRG41 and ICPL85063 in response to Cd treatment indicating heavy metal sensitivity of LRG41 and ICPL85063.
