种子异形性为植物提供了在不利环境中生存的替代策略，这不仅可能增加成功萌发的机会，还可能对后代的性状产生影响。然而，曹等人。研究发现，碱蓬种子的不同特性(即黑色和棕色)对其后代的生长和对盐分的生理反应没有影响：所有后代都需要盐分才能最佳生长和适应其自然栖息地。
Seed heteromorphism provides plants with alternative strategies for survival in unfavourable environments, which may not only increase the chances of successful germination, but may also have an impact on characters of the descendants. However, Cao et al. found that the different properties of the dimorphic seeds of Suaeda aralocaspica (i.e. black and brown) had no effects on their descendants' growth and physiological responses to salinity: all descendants required salinity for optimal growth and adaptation to their natural habitat.
