The study investigated the sensitivity of Aegilops geniculata Roth to salinity stress from varying concentrations of potassium chloride (KCl) during seed germination and early seedling development. The research utilized five accessions of Aegilops geniculata Roth sourced from the Genebank of Bulgaria’s working collection. A completely randomized experimental design was employed, incorporating seven KCl concentrations (0 mM - control, 50, 100, 150, 200, 250, and 300 mM), with two replicates per treatment. Results revealed significant adverse effects on germination rates and seedling traits, except for an extended germination period under saline conditions. Notably, shoot growth was more hindered by high salinity than root development, particularly at 300 mM KCl. At this concentration, all genotypes except BGR43677 failed to germinate or sustain shoot and root growth. In contrast, the BGR43677 genotype exhibited exceptional salt tolerance, maintaining viable germination and promoting both shoot and root growth under extreme salinity. These findings underscore the variability in salt tolerance among A. geniculata accessions and highlight BGR43677 as a promising candidate for further study in saline environments.
