Abstract :

In the pot experiment, O. tenuiflorum L reduced their root length, shoot length and dry biomass with increased concentrations of Cu, Cr and Cd over the control, and reduction trend observed for metal treatment was Cu>Cr>Cd after 80DAS. SOD–FSRA, H–RSA, DPPH–FRSA and phenoilc content was more in leaf>shoot under Cu treated plant as compared with Cr and Cd. Maximum accumulation of Cu, Cr and Cd in the plant was 39.8ppm at 30 mg Kg–1 Cu treated pot, 21ppm at 10 mg Kg–1Cr treated pot and 16ppm at mg Kg–1 Cd treated pot respectively, recorded after 80DAS. Hence, the result of metals in plant indicates that more than the permissible limit (WHO) and should not advisable to use plant as a medicinal treatment without metal analysis.
