Popis: | In model experiments in sand culture the wildgrowing species of fam. Brassicaceae flora of the North Caucasus: Alyssum murale Walds. et Kit., A. alyssoides (L.) L., A. campestre (L.) L., Erysimum ibericum (Adam.) DC. were studied for the effects of high concentrations of Ni (1 and 2 mM) on storage capacity and sustainability indicators: biomass accumulation, the level of photosynthetic pigments, the balance of mineral elements. The experimental variants show a different degree of increase in Ni concentrations in compared species, the maximum - in hyperaccumulator A. murale . On the basis of variability of sustainability indicators we compiled a sequence of species tolerances to Ni: A. murale > E. ibericum > A. campestre > A. alyssoides . Species E. ibericum can be used for phytostabilization of Ni contaminated areas and species A. murale and A. campestre - for phytoextraction of nickel from soils. |
