Comparison of salt tolerance among some bread and durum wheat cultivars in germination and seedling development stages.

Abstract

A Comparison laboratory trait was conducted to compare the effect of salinity levels on germination and seedling growth of some bread and durum wheat cultivars. Two groups of wheat cultivars , the first include the bread wheat cultivars Sham – 6 and sabah , and the second include the durum wheat cultivars Dor -29 and Alnaama , were grown under salinity levels 0,3,6,9,and 12 ds/m for two weeks in 25 c .The balanced groups in split blot design with three replications was used. The results showed a significant decrease in water uptake , shoot and root length and their dry weight with the increasing of salinity level, in addition to delayed the germination in all cultivars . The group of durum wheat surpass the bread wheat group in all studied characters . Dor-29 showed the highest values in all characters. There were a significant differences between the bread wheat cultivars and a significant interaction between salinity levels and cultivare within bread wheat cultivars group in root and shoot length and dry weight .
