    Abstract:
    A pot experiment was conducted to study the effects of salt (ST), waterlogging (WL), and their combination (SW) at post-anthesis on the grain yield and its starch and protein components of wheat cultivars Yangmai 12 and Huaimai 17. Comparing with the control, treatments ST, WL, and SW, especially ST and SW, decreased the allocation of nitrogen and carbon assimilates at pre- and post-anthesis to the grains significantly, resulting in an obvious decrease of grain yield and its protein and starch contents. Both ST and SW had significant negative effects on the glutenin/gliadin and amylase/amylopectin ratios in the grains, compared to CK and WL. Yangmai 12 was more sensitive to ST than SW, while Huaimai 17 was in adverse. WL decreased the accumulation of protein and starch in the grains of the two cultivars. Except that the glutenin and albumin in Huaimai 17 had some increase, the globulin and gliadin in Huaimai 17 and all protein components in Yangmai 12 were decreased under WL.
