Healthy seed germination is critical for the growth cycle of
plants, and determines the establishment of seedlings and subsequent crop
production. High salinity conditions can result in difficulty for seed
germination and delays the germination period. Development of salinity tolerant
genotypes through screening and selection is one important strategy to overcome
this case. In the present study, the effects of salinity (0 mM NaCl (control=
distilled water)), (50 mM NaCl (slight salt stress)) and (100, 150 and 200 mM
NaCl (high salt stress)) had gradual and negative effects on seed water uptake
and germination attributes. The results verified a remarkable variation for
genetic materials ability under salinity conditions. Overall, among 14 wheat
genotypes (Sids-12, Nielien and Weiber) genotypes were seemed to be relatively
salt tolerance and (Gimeza-12, Diebera, Misr-1, Katela) genotypes were seemed
to be moderately tolerant genotypes to salt stress, which were attributed to
higher germination percentage, seedling length, seedling fresh and dry weight,
tissue water content, vigor index and tolerance index. On the other hand, the
genotypes (Shandaweil-1, Giza-168, Misr-2, Sids-1, Sanora, Gimez-7 and
Sakha-94) were found to be moderately to strongly sensitive toward salt stress
conditions. This systematic method is able to identify genetic variation in
salinity tolerance in studies breeding material or in a large number of
genotypes of wheat, and help to make account of differences with respect to
salinity conditions.
