Physiological, Biochemical and Growth Responses of Lady’s Finger (Abelmoschus esculentus L.) Plants as Affected by Cd Contaminated Soil

摘要

Cadmium contamination of the soil is a common cause of environmental concern in the suburban areas of developing cities in India The present research paper describes the changes in physiological, biochemical, growth and yield characteristics, and bioaccumulation potential of lady’s finger (Abelmoschus esculentus L.), an important vegetable crop at different levels of Cd in the soil. Cadmium accumulation was maximum in roots followed by stems, leaves and fruits at 100 mg Cd kg−1 in the soil. Cd accumulation in lady’s finger negatively affected the physiological and biochemical characteristics, growth and yield. The magnitude of negative effect enhanced with increasing Cd concentration. The study suggests that due to higher potential of bioaccumulation of Cd in lady’s finger and consequent reductions in growth and yield, this plant may not be a suitable option for cultivation in Cd contaminated soil.
