How does alstroemeria prevent self-pollination?

Answer 1

Alstroemeria, also called lily of the Incas or Peruvian lily, is native to South America. Propagation is most commonly and easily achieved by division of the bulbous root system, but this method produces only clones of the parent plant. The best way to reliably mix the strains of different Alstroemeria plants is by hand pollination. The flowers resemble lilies with large open petals and pronounced stamens and pistils.

Answer 2

Alstroemeria prevents self-pollination through a mechanism called dichogamy. This means that the male and female reproductive organs mature at different times within the same flower. The stigma, which collects pollen, is usually receptive before the anthers, where the pollen is produced, release their pollen. This helps ensure that pollen from other flowers is transferred to the stigma instead of self-pollination occurring.
