Acanthus ilicifolius L. a promising candidate for phytostabilization of zinc.

The potential of a halophyte species-Acanthus ilicifolius L.-to phytostabilize zinc (Zn) grown under hydroponics culture conditions was critically evaluated in this study. The propagules after treating with ZnSO (4 mM) were analysed for the bioaccumulation pattern, translocation rate of Zn to the shoot, effects of Zn accumulation on organic solutes and the antioxidant defence system.

Structural changes in response to bioaccumulation of iron and mercury in Chromolaena odorata (L.) King & Robins.

A comparative study was designed to elucidate the effect of iron and mercury on the morphological and anatomical changes as well as bioaccumulation potential in Chromolaena odorata. Plants were grown in half-strength Hoagland nutrient medium artificially contaminated with known quantities of HgCl2 (15 μM) and FeCl3 (1000 μM). Bioaccumulation of Hg and Fe was maximum in the root, and comparatively reduced bioaccumulation was recorded in the stem and leaves.
