Surface pollination Surface pollinationIn these the pollen floats on the surface and reaches the stigmas of the female flowers as in Hydrilla, Callitriche, Ruppia, Zostera, Elodea. Seed production in monoecious and dioecious populations of Hydrillla. Growing your Hydroponic vegetable garden inside can have its many perks.Not all vegetable plants produce dry pollen to be carried by wind to produce fruit, this type of pollination called Anemophily.instead so many vegetables like Cucurbits crops rely on attracting insects for pollination to produce fruit, when the pollination occurs by insects/animals is called Entomophily. Both biotypes depend on tubers for overwintering, although monoecious hydrilla exhibits a more annual habit than the dioecious type, with abundant tuber/turion production around September (Owens et al. 2002.
