Cadmium tolerance and its absorption ability in fibre flax and linseed varieties

Cadmium pollution now is one of the main environmental problems. Growing of plants hyper accumulators of Cd can help to remediate the polluted soils. Species Linum usitatissimum L. is one of such crops. Six fibre flax and two linseed varieties were evaluated for their resistance to different cadmium sulfate 8/3-hydrate 3CdSO4 × 8H2 O concentrations at the seedlings stage in the Jacobsen apparatus. After this, two fibre flax and two linseed varieties were selected and tested for adult plants’ cadmium resistance and absorption ability. Cadmium concentrations were analysed in the ashes of adult plants by x-ray fluorescence analyzer BRA – 18. The presence of pollutants did not influence flax germination ability, but tested genotypes showed different degrees of cadmium resistance. They also differed in dynamics of growth and development suppression affected by Cd contamination, which probably is caused by different mechanisms of resistance. Fibre flax varieties Svetoch and Priziv 81 appeared to be more susceptible to pollution and absorb less cadmium per mass unit than linseed varieties Voronezhskiy 1308 and Bakhmalskiy 1056. So, high cadmium absorption ability of the plant provides its relative resistance to contaminant toxic influence by immobilization of metal ions. Obtained results also show the possibility of selection of genotypes with high cadmium resistance and absorption ability.
