Cadmium induced changes on proline, antioxidant enzymes, nitrate and nitrite reductases in Arachis hypogaea L.

The groundnut, Arachis hypogaea seedlings, when grown in pot cultures for 10-25 days at 25, 50, 100 microM CdCl2, showed a marked decline in growth compared to control. Similar trend was observed for nitrate reductase (NR) and nitrite reductase (NiR) activities whereas proline, peroxidase (POD) and catalase (CAT) showed increasing trend when observed on the 10th day of the experiment. Changes have occurred in the physiological and biochemical activities which are observed even at low Cd levels (25 microM).

Effect of industrial effluent on the morphological parameters and chlorophyll content of green gram (Phaseolus aureus Roxb).

A pot culture experiment was conducted to study the effect of biomass power plant effluent on seed germination, seedling growth and chlorophyll content of green gram (variety LGG 460) have been estimated at different effluent concentrations and time intervals. The effluent is alkaline in nature (pH 8.5), odorless, and comprises of heavy metals such as Cr (0.

Phytotoxicity of cadmium on protein, proline and antioxidant enzyme activities in growing Arachis hypogaea L. seedlings.

Phytotoxicity of cadmium on growing Arachis hypogaea L. seedlings was studied. Seeds were exposed to 25, 50, and 100 micromol/L CdCl2 concentrations, for a period of 10, 15, 20 and 25 d.
