porogamy [pȯ′räg·ə·mē]
(botany) Passage of the pollen tube through the micropyle of an ovule in a seed plant. Porogamy the usual route by which a pollen tube enters an ovule—via the micropyle—in the fertilization of angiospermous and gymnospermous plants. When the pollen tube penetrates the ovule by a different route, the process is called aporogamy (for example, penetration of the chalaza is known as chalazogamy). Want to thank TFD for its existence?
