Type of Anion Largely Determines Salinity Tolerance in Four Species.

The aim of the present study was to compare the effect of various salts composed of different cations (Na, K) and anions (chloride, nitrate, nitrite) on growth, development and ion accumulation in three species with accessions from sea coast habitats ( and ) and from an inland habitat. Plants were cultivated in soil in an experimental automated greenhouse during the autumn-winter season. Nitrite salts strongly inhibited growth of all species, but was the least sensitive.

Salinity and Heavy Metal Tolerance, and Phytoextraction Potential of Plants from a Sandy Coastal Beach.

The aim of the present study was to evaluate tolerance to salinity and different heavy metals as well as the phytoextraction potential of plants from a brackish coastal sandy beach habitat. Four separate experiments were performed with plants in controlled conditions: (1) the effect of NaCl gradient on growth and ion accumulation, (2) the effect of different Na and K salts on growth and ion accumulation, (3) heavy metal tolerance and metal accumulation potential, (4) the effect of different forms of Pb salts (nitrate and acetate) on plant growth and Pb accumulation. A negative effect of NaCl on plant biomass was evident at 0.
