Salt stress can harm crop plants, but some species like amaranth and quinoa can handle it well. Amaranth is especially good at growing in salty soil without losing grain production. It does this by having fewer stomata on its leaves, which helps it keep water better than quinoa. Amaranth also stores salt differently in its roots, stems, and leaves compared to quinoa. The genes that help amaranth deal with salt are more active in its roots than in quinoa. Overall, amaranth and quinoa have different ways of dealing with salt stress, with amaranth showing more promising results.
