Effect of Salinity Stress on Grain Protein and Its Component Accumulation in Wheat

The relationship of soil salinity content with grain protein and its component contents and accumulation amounts in wheat was analyzed.The results indicated that grain protein content increased with the rising of soil salt content,while protein accumulation amount in grains decreased.The difference of grain protein content and accumulation amount between S1 and S2 treatments was significant,while the differences between S3 and S1,and between S3 and S2 were very significant.The content of each protein component increased with soil salt content.The difference on contents of albumin,globulin glutenin and gliadin among 3 soil salt content treatments was significant or very significant.The ratio of albumin,globulin and glutenin contents to protein content decreased with rising of soil salt content,whereas the ratio of gliadin content to protein content increased.
