Examples from Classical Literature As the result of the pollination the ovary developes into a dry 1-seeded indehiscent fruit. Pollination in Vallisneria is epihydriphilous. Epihydrophily :Plants which are pollinated outside the water. Vallisneria's male flower or pollen grain are released on the surface of water, which are passively carried away by water currents; some of them eventually reach the female flower (ii) Those that distribute it beneath the surface.

Hydrophily (Water Pollination): (Gk, Hydro = water and Philein = to love) Hydrophily takes place only in few aquatic plants. flowers and have the same manner of pollination as their terrestrial ancestors (Arber, 1920; Scul-thorpe, 1967). Pollen can be transferred to one plant or even a nearby plant so that they can get fertilized and make more flowers. Example: Vallisneria. Pollination in Vallisneria spiralis: It is a dioecious, submerged and rooted hydrophyte. See our Privacy Policy and User Agreement for details. Zoophily. Examples: Vallisneria spiralis, Elodea.

In case of fully submerged plants, the flowers are either pollinated via the water current, called hypohydrophily. Examples: Vallisneria (Ribbon weed) Pollination is a process in which pollen is transferred to the female reproductive organs of seed plants, thereby enabling fertilizationand reproduction through growth of the pollen tube and eventual release of sperm. See our User Agreement and Privacy Policy. Hydrophily is of two types: Hypohydrophily Plants which are pollinated inside the water. Looks like you’ve clipped this slide to already.

The female plant bears solitary flowers which rise to the surface of water level using a … Hypohydrophily is a true hydrophily that occurs beneath the surface of water. Two general, but sometimes rather arbitrary, forms of hy drophily are recognized: 1) epihydrophily; pollination via pollen transport at the water surface (two-dimensional), and 2) hypohy drophily; pollination via pollen … In Epihydrophily pollination take place on the surface of water. Specific gravity of pollen grains is equal to that of water, so they float on water. ›¬¶¡C(9yýüõ³%¼¯Ä[NÉ­u’[8!±>ǁïU¦"šÂ‚Ha¡è6–¦!ð`0!¢Àºðž}=6Xƒñ-DDr÷ú'E\¨¬´Ž¬¾¶ºÙ\a`ï¶ ;º°±$ãÑÑt"´½; ígÀ` ¬}ÕX)Ëüwqä­w2$ƒ÷í¦±ða£v×sÁø;|þrzT º£(¼h!Èÿ‹3Á¯ ið2¼o‘!)˜2œ! 3.

SELF POLLINATION It is the transfer of pollen grains from the anther of a flower to the stigma of either the same or genetically similar flower. The usual agents are wind, animals and water. Hypohydrophily occurs below the surface of water, e.g., Zostera, Ceratophyllum. There charitaceae-epihydrophily), underwent a parallel evolu- are four types of pollination mechanisms in Hydrochar- tion. The female flower have a very long pedicel, therefore it reaches the surface of water. Pollen grains are long, without exine, heavier than water , sink down to meet stigma of female flowers. âRKõ“f9K½Ÿ|kY^FÌ#¢7³àH° Hg”˜òÁEÃ,pÚ xøR¯ÛîuÙ=ý°„.e§'ãÄÑ×îP§rà‡ø^€—áÅ°Wx#Þ®÷9CþAÚ¶ƒ–‡(±ô è¬Ê_Á¦áÏ!¦í¯~:“£T‚Z›áÅà7pÝÚâÔ±Ó¸_:4Љ‹†K‡h¨©P‚N¸°ÒÓ151Zœ&"ŠUU”ÕÕVAá^ßßÛŠÕ f˜žQ´ÊBXŒÐX˜Òˆåi âŸç{óÐ$"t¼4 ÑEæ¡®p`(0ê€ãÛñb‡ê«¸«½Y›D„3ij¬55°´zÊ&ª3TÖê+A˜òÀÿâ‡ø^€—áÅx‹¹ÑÐdªÃ‡X›­–F¼Î¶&|Ì&þ40è¬ÞF•Ø;˜ There are two types of hydrophily: Epihydrophily and Hypohydrophily.

Flowers are small, colourless, inconspicuous, nectar less and become arranged as inflorescence. • Pollination takes place through water. • All aquatic plants are not hydrophilous. It is of two types. Cross-pollination is mainly seen in dark and bright colored flowering plants, where insects like butterflies and honey bees are attracted by their bright colored flowers. Pollination by animals is called Zoophily. Hydrophilous species fall into two categories: (i) Those that distribute their pollen to the surface of water.
