Dichogamyas in the avocado, is a natural mechanism by which plants avoid self pollination within the same flower autogamy thus reducing inbreeding and, conversely, promoting outcrossing. Dichogamous flowers are either protandrous or protogynous. Protogyny is the reverse of protandry. The stigma of protogynous flowers, as in the water lilies Nymphaea spp. Flower types also differ depending on whether they open or remain close during the pollination period click here to read Types of Pollination.
