The ability of seeds to germinate at high salt concentration in the soil is crucial importance for the survival and perpetuation of many plant species. Therefore, we examined effects of different concentrations of NaCl (200, 400, 600 and 800 mM) on germination of four species from fam.
Salts may accumulate on the soil surface because they can-not leach out of the root zone.Plants can also be damaged by salt effects or toxic-ity. In saline and saline-sodic soils, high concentrations of soluble salts reduce the amount of available water for plants to use.his phenomenon may not occur in very sandy soils. because they lack clay content. Salt problems. When salts accumulate in soils, problems arise for. two main reasons: the soil becomes less permeable, and the salt damages or kills the plants.
