Abstract

Effects of various concentrations of copper were studied on growth performance, dry matter production and photosynthetic pigments of Ludwigia perennis L. The growth of the plant showed significant negative correlation with increase in concentration of copper. Higher concentrations of copper caused maximum reduction of shoot and ischolar_main dry weight over the control plants. The reduction in dry weight of ischolar_main was higher than the shoot. The photosynthetic pigments also showed reduction with increasing concentration of copper.

Abstract

In the present study, different heavy metals like copper, zinc and mercury were recorded in water and soil samples at different sites along Alaniya river system. Higher concentrations of these metals were recorded at polluted sites compared to non-polluted site of the study area. Soil samples showed higher concentration of metals compared to water samples. The vegetational analysis of the study sites observed higher number of plant species at non-polluted site, while less number of plant species were present at polluted sites. Some plant species were recorded only at the non-polluted sites but absent at polluted sites.
