Abstract
Mustard (Brassica junccea) is an oilseed crop in Bangladesh. Its oil content varies from 42 - 45% based on genotypes and growing conditions. This crop may be useful in soil reclamation as phytoremediation and phytoextraction of toxic heavy metals such as cadmium (Cd) from soil. Therefore, identication of phytoremediation potential B. juncea genotypes that accumulate heavy metal in their vegetative parts with less transportation to seedss would be of great importance for reclaiming the heavy metal contaminated soil. Eleven commonly grown B. juncea genotypes in Bangladesh were investigated to determine the phytoremediation potential against Cd stress. Among 11, genotype Sambal and Daulat showed maximum reduction in plant height (42%), leaves number (45%), leaves greenness (63%), root length (25%), shoot dry weight (34%) and root dry weight (34%), siliquae number (40%) and yield (34%) compared to their control. Sambal and Daulat accumulated maximum amount of Cd in vegetative parts. In contrast, the genotype BJDH17 showed maximum reduction of different phenotypic traits and minimum Cd accumulation in vegetative parts. We found minimum Cd translocation from root to shoot and shoot to seeds in the genotypes BJDH17 and BJDH20. Sambal and Daulat had the highest bioaccumulation coefcient (BC), whereas BJDH17 had the lowest in under Cd stress. Present ndings help us in selecting genotypes suitable for phytoremediation to reclaim the soil against Cd stress and safe for cultivating as commercial varieties in heavy metal contaminant soil, like in industrial areas.
