What are dioecious and monoecious plants

Flowering plants

When we want to grow our own plants by obtaining seeds from these same vegetables, we have to take into account how they multiply naturally; that is, what organs do their flowers have to allow the development of a new generation.

Therefore, in gardening it is very important to know what are dioecious and monoecious plants, since knowing your answer will save us more than one headache 🙂.

What are dioecious plants?

Avocado blossoms

Dioecious plants are those that little by little we are leaving, unfortunately, a little aside as they are not very profitable. They are those that are distinguished between male and female specimensTherefore, for fertilization to occur, the pollen of the former must fertilize the ovary found in the flowers of the latter.

Yellow tulips

Monoecious plants are gaining ground over dioecious ones, at least in gardens and orchards. They are vegetables that present the male and female organs on the same floor. There are three types:

  • Monocline-monoecious: they present the reproductive apparatus in the same flower, such as the Tulipa sp (tulip).
  • Diclino-monoecious: the same plant has male flowers and female flowers, such as the zea mays (corn).
  • Polygams: a single plant has hermaphroditic and unisexual flowers, such as the Carica papaya (papaya).
