Question

Under which conditions in flowers autogamy becomes a rule?

Answer 1

Autogamy:

1. Autogamy, also known as self-fertilization, is the union of two gametes from the same individual.
2. The most prevalent type of autogamy is self-pollination, a reproductive strategy adopted by many flowering plants.
3. The primary mating technique present in many vegetables and grain crops is self-pollination, or more precisely almost full self-pollination.
4. The bulk of the world's 50–60 major grain crops are primarily self-pollinated.
5. In other words, domestication did not lead to the evolution of self-pollination in grain crops.
6. Autogamy, also known as self-fertilization, is the union of two gametes that originate from the same person.
7. The most common manifestation of autogamy is self-pollination, a reproductive strategy used by many flowering plants.

Conditions:

1. Bisexuality, synchronicity in pollen release, and stigma receptivity are essential for autogamy, and the anther and stigma should be near to each other.
2. Cleistogamy is a condition in which flowers do not bloom so only self-pollination occurs in such flowers.
3. For example, Commelina benghalensis has underground flowers with Homogamy — stamens and carpels mature at the same time, resulting in self-pollination. Mirabilis jalapa (4 o'clock plant) is an example.
