This was also investigated in the greenhouse. The procedure was to decapitate the seedlings at various stages of growth. In contrast, no response was found for the diploid plants. Before frost came, all the above healthy field-grown plants were moved to the greenhouse. If their growth, or regeneration of propagules, is continued next year, it would prove that the perennialism is present in these plants.
Perennial maize is of great importance in crop improvement and production.
If its basic genetics, particularly at the molecular level, is fully explored, new directions in maize farming will be established in the near future. For instance, like sugar cane, once it is planted, continued harvests can be reaped for several years.
