What Does Monoecious Plant Mean?
A monoecious plant is a plant where both the male
and female reproductive systems exist on the same plant. Monoecious plants possess some flowers that are
female and others that are male. Species that are able to pollinate themselves are considered self-pollinating.
Maximum Yield Explains Monoecious Plant
Corn is an excellent example of a monoecious
plant. The developing ear of corn is the female reproductive portion and the tassel is the male. The female portion or ear
contains the pistil and stamen for the plant, and the tassel or male portion
contains the pollen, which at the proper time will fall onto the silk to
pollinate the corn.
In corn the male portion or tassel may be removed
and the ear or female portion of the plant may be artificially pollinated by
hand for the creation of an entirely new variety. Such cross-pollination is
common in modern plant science.
One drawback to self-pollinating monoecious plants
is the danger of cross-pollination, which occurs when the pollen of the same
species but from a different variety falls onto the female stamen of a different
variety of the same species.
This can be a concern, because
exactly what the resulting hybrid may be is often unpredictable.
Some monoecious plants are self-sterile, which means they require the pollen of another plant in order to pollinate.
