Phenotypic Traits and Seed Vigor of Maca Seeds with Different Colors

  • Received Date: 2014-09-17
  • The size, germination, seeding growth and enzyme activity of the brown-yellow, brown-red and black maca (Lepidium meyenii) seeds were analyzed. And the correlation between seed phenotypic traits and seed vigor was studied. The results showed that there were no difference between the traits of the brown-yellow and black seeds, including length, thickness, ratio of width and thickness, kilo-grain weight, germination energy, germination percentage, germination index, vigor index, seedling length, root length, fresh weight and dry weight of each plant, POD and dehydrogenase activity; while the traits of both brown-yellow and black seeds were significantly higher than those of the brown-red seeds (PPPP<0.01). Therefore, the vigor and germination ability of brown-yellow and black seeds were better than that of brown-red seeds.
