Sažetak
Salinity is one of the major problem in agriculture resulting in loss of yield and in fields it often occurs in the combination with drought. In plants, salinity causes both osmotic and ionic stress. Aside it causes the perturbations at morphological, physiological and biochemical level accumulation of NaCl in plants can be toxic for the plant. In this study winter wheat genotypes (BC Bernarda and BC Tena) were used to test their resistance to salinity. The seeds were sown in pots and exposed to 0, 90, 160 and 230 mM NaCl for five days. Seedlings were grown under 12h light /12h dark photoperiod and artificial illumination at 23±2 ⁰C. The germination was tracked from 2nd day while shoots and roots length was recorded last day of experiment. The higest NaCl treatment (230 mM) reduced shoots and roots compared to 0, 90 and 160 mM in both genotypes indicating that this salt level impeded growth. Germination percentage at 230 mM NaCl in both genotypes after 2nd day of the experiment decreased for 307.7% compared to control while at 160 mM NaCl inhibition of germination was from 47.1% in BC Bernarda to 56% in BC Tena. These results suggest that NaCl had greater negative impact in early stages of germination. Comparing variations among genotypes, from 3rd to 5th day of experiment BC Tena had higher germination percentage at all NaCl levels than BC Bernarda indicating that it poses the greater salt tolerance. Present study reveales different genetyc background of tested genotypes related with salinity resistance.
