Solni stres pripada skupini abiotskih stresova koji smanjuju rast i produktivnost većine usjeva, a pšenica nije iznimka. Cilj ovoga istraživanja bio je ispitati varijabilnost svojstava klijavosti različitih vrsta roda Triticum u uvjetima abiotskog (solnog) stresa. Istraživanje je provedeno na sedam vrsta (podvrsta) roda Triticum, koje su tretirane različitim koncentracijama NaCl (0 mM, 50 mM, 100 mM i 150 mM). Za naklijavanje sjemena korištena je metoda rolanog filter papira. Ispitivana su sljedeća svojstva: energija klijanja, ukupna klijavost, duljina glavnog korjenčića, duljina izdanka, svježa masa biljčica i suha masa biljčica. Istraživanjem je utvrđeno značajno variranje ispitivanih svojstava klijavosti kako između različitih genotipova tako i između različitih razina tretmana. Analizom varijance utvrđen je statistički značajan utjecaj genotipa, tretmana i njihove interakcije na sva ispitivana svojstva klijavosti. Kod većine genotipova, povećanjem koncentracije NaCl opadale su vrijednosti energije klijanja, ukupne klijavosti, duljine korjenčića, duljine izdanka i svježe mase biljčica, dok je za svojstvo suhe mase biljčica uočen suprotan trend. T. spelta i T. sphaerococcum izdvojili su se kao genotipovi kod kojih je većina ispitivanih svojstva pokazala minimalno variranje u uvjetima solnog stresa., Salt stress belongs to the group of abiotic stresses that reduce the growth and productivity of most crops, and wheat is no exception. The aim of this study was to examine the variability of germination properties of different species of the genus Triticum under conditions of abiotic (salt) stress. The study was conducted on seven species (subspecies) of the genus Triticum, which were treated with different concentrations of NaCl (0 mM, 50 mM, 100 mM and 150 mM). The rolled filter paper method was used for seed germination. The following traits were examined: germination energy, total germination, main root length, shoot length, plant fresh and dry mass. The research revealed a significant variation of the examined germination traits both between different genotypes and between different levels of treatment. Analysis of variance revealed a statistically significant influence of genotype, treatment and their interaction on all examined traits. In most genotypes, the values of germination energy, total germination, root length, shoot length and plant fresh mass decreased with increasing NaCl concentration, while the opposite trend was observed for the plant dry mass. T. spelta and T. sphaerococcum were marked as genotypes in which most of the examined traits showed minimal variation under salt stress conditions
