Accumulation of cadmium in potential hyperaccumulators Chlorophytum comosum and Callisia fragrans and role of organic acids under stress conditions

Original language description

Cadmium (Cd) accumulation, antioxidant activity (AOA), chlorophyll fluorescence (F) and organic acid distribution in Chlorophytum comosum and Callisia fragrans plants exposed to artificially added Cd (40, 160 and 320 mg kg−1) were examined in pot experiment. At the highest Cd concentration, C. comosum accumulated in roots and the aboveground parts up to 1331 and 1054 mg Cd kg−1 DW, and C. fragrans up to 1427 and 1263 mg Cd kg−1 DW, respectively, which are quite near at the level of hyperaccumulator. Cd accumulation in both plant species increased significantly with the increment of soil Cd dosage, and the distribution was roots &gt; shoots &gt; stolons. Values of BC showed rising trend indicating an accumulation potential of both species. The root AOA was positively correlated to Cd addition, especially in C. comosum. Higher values of free SA were found in roots with a significant enhancement at concentrations of 40 and 160 mg kg−1 Cd. It was observed that citric acid significantly reacted in both species, while fumaric acid only in C. comosum in response to Cd which may contribute to Cd chelation. Our data indicate that both species are suitable for phytoextraction of Cd from contaminated soils which increases their value as ornamentals.
