The study aims to evaluate the response of three varieties of celery (Apium gravelolens L.), a local variety (Guemare) and two introduced varieties: TalluTah (French) and Elne (Danish). The experiment was carried out in a plastic greenhouse, under highly salt concentrations of irrigation water (3.08, 15.9 and 27.3 ms/cm). In the final stage of plant growth, dry biomass indices in the leaves were measured. The results confirmed a difference in the response of studied celery varieties, and increased salinity of irrigation water resulted in a significant decrease in the specific leaf area (SLA), an increase of the specific leaf weight (SLW), and a non-significant increase in the leaf tissue density (D). The results also showed that the Danish variety (Elne) was more tolerant to salt stress, and we recommend cultivating it in areas suffering from salinization.
