Abstract Response of two wheat cultivars to different levels of soil salinity: The target of the work described in part I. was to study the effect of salinity levels on growth, grain yield and its components of two wheat cultivars. A greenhouse experiment was carried out using Triticum aestivrtm L., cultivars, Sakha 8 and Sakha 61, Chloride type salinization was applied to soil and the soil salinity levels used (on soil dry weight basis) were 0.0, 0.2, 0.4, 0.6% in a randomized complete block design with three replicates. In both cultivars, all growth and yield characters were reduced by increasing soil salinity. The most sensitive yield components was grains number per spike, but number of spikelets/spike is the least sensitive components at all levels of salinity. Yo significant differences in grain yield between the two cultivars. The retarded of growth of wheat parts under salt stress was therefore resulted from reduction of the leaf area for photosynthesis. |
