Abstract
A greenhouse experiment was conducted to study the effects of cadmium (Cd) on growth, biomass yield, and Cd uptake in three radish (Raphanus sativus L.) varieties at the Indian Institute of Horticultural Research, Bangalore, India, during 2008–2009. Plants were subjected to different Cd levels by application of cadmium nitrate [Cd (NO3)2] at the rates of 0, 50, 100, and 200 mg Cd kg−1 soil. Length and fresh and dry biomass yields of shoots and roots decreased because of the phytotoxic effect of Cd. Among three varieties, Japanese White Long showed the greatest sensitivity to Cd toxicity. The accumulation of Cd in shoots and roots was greatest in Japanese White Long, which had greater bioconcentration factor values. Variety Arka Nishanth recorded lower bioconcentration factor values and greater transfer coefficient values, indicating lower Cd accumulation in root tubers in this variety. Hence, variety Arka Nishanth can be preferred in Cd-contaminated soils.
