EFFECT OF SELENIUM AND CADMIUM IN CHLOROPHYLLS AND CAROTENOID CONTENT OF PHASEOLUS AUREUS ROXB

Abstract

In greenhouse, seeds of Phaseolus aureus Roxb. local class are germinated in pots. The seeds treated with different concentrations of Cd (0.0, 0.01 and 0.05M, as CdCl2), a unique concentration of Se (0.05 M, as Na2SeO3) and as a combination with Cd, in addition to a control (distilled H2O). In P. aureus, there was significant decreasing in all chlorophylls content. Generally, treatment with Se enhanced the content of chlorophyll which increased significantly in comparison with the control (dH2O). The combination of Se + Cd, 0.05M caused increasing in chlorophyll b and carotenoid significantly comparing with Cd alone at 0.05M. These results indicate the antagonistic effect between Se and Cd on chlorophyll and carotenoid contents
