Cadmium Uptake by Sugarcane Grown in Contaminated Soil

Abstract

This research was to study the capacity of cadmium removal from soil by sugarcane grown in pot experiment. The experiments were designed in a Factorial Randomized Complete Block Design with three replicates. The amounts of cadmium nitrate (Cd(NO 3 ) 2 .4H 2 O) added to the pot experiments were 0, 10, 20 and 40 mg Cd kg soil (dry weight). Sugarcane samples were harvested after two growth periods, three and six months. After harvesting, the canes were botanically separated into five parts: root, underground stem, bagasse, juice, and leave. The results showed that Cd uptake capacity from soil on experimental pot was 38.96 and 31.64 mg kg in treatment of 40 mg Cd kg, at three and six months, respectively. Accumulation of cadmium in various parts of sugarcane of experimental pot was the most accumulate in roots was 96.56 mg kg following by underground stem, bagasse, leaves and juice, at the sixth month. §” ”§—≠ : °“√¥Ÿ¥¥÷s ·§¥‡i’¬i OâO¬
