Abstract

Little is known about seed GERMINATION responses of Iranian WHEAT cultivars to SALINITY stress. In order to evaluate salt tolerance of an array of Iranian common WHEAT cultivars at GERMINATION and early seedling stages, an indoor expriment was conducted using different NaCl SALINITY levels of 0, 3, 6, 9, 12 and 15 dsm-1 in a 3 replicated RCBD. Among 30 cultivars used in this study, one, i. e. Karchia-66, is known for its resistance to SALINITY, eight have been reported tolerant by some workers, and the rest are likely to be non- tolerant. The results showed that with an increase in SALINITY levels different GERMINATION idices were significantly affected. Mean comparisons between the cultivars revealed that 15 cultivars of WHEAT had the highest rates of germiantion stress index, with Karchia-66 being the single most resistant followed by Bistoon, Chamran, Alamoot, Darab 2, Bezostaya, Pitik, Inia 66, Azadi, Bolani, Tajan, Atrak, Niknezhaad, Mexipak and Arvand. Considering this index and the final GERMINATION percent, nine cultivars including Karchia-66, Chamran, Bistoon, Alamoot, Bezostaya, Azadi, Atrak, Niknezhaad and Mexipak showed the highest rates of salt tolerance. Based on the three indices of GSI, FBPI and GERMINATION rate the two cultivars of Karchia-66 and Chamran are categorized as the cultivars with he highest degree of salt tolerance. A number of cultivars previously reported as salt tolerant did not show a considerable tolerance to SALINITY stress. Thus, it was concluded that evalution of the cultivar performance based on SALINITY tolerance at GERMINATION stage may not reflect their responses to SALINITY stress in other stages of the growth.
