Seed heteromorphism is an important strategy of plants for adapting to heterogeneous environments, and the effect of heteromorphism on the descendant is worth studying in detail. In the present study, a comparison of the physiological responses to salinity stress between the brown seed plant and black seed plant of Chenopodium album (Imbikicane) was performed by analyzing the effects on growth and physiological changes under different concentrations (0, 50, and 300 mmol/L NaCl) of salt stress. The results indicated that the growth characteristics (plant height and branch number) of plants from the brown seed performed better than those of plants from the black seed under various salt concentrations. In addition to electrolyte leakage, for which the black seed plant had significantly higher values than the brown seed plant, all salt tolerance-related indices, such as oxidative damage parameters (O₂^.-, MDA), antioxidants (Car, AsA), antioxidant enzymes (SOD, CAT, POX), and osmolytes (Soluble sugar, Pro, and GB) showed no significant difference between two types of plants. This suggests that the difference between early growth characteristics of the two types of plants might be caused by diverse differences in the seed embryo size and germination speed, which did not to apply to the antioxidative system.
