pol·li·nate

 (pŏl′ə-nāt′)
v. pol·li·nat·ed, pol·li·nat·ing, pol·li·nates
1. To transfer pollen from an anther of an angiosperm to (a stigma, flower, or plant).
2. To transfer pollen from a microsporangium of a gymnosperm to (an ovule, cone, or plant).

[New Latin pollen, pollin-, pollen (from Latin, fine flour) + -ate.]

pol′li·na′tion n.
pol′li·na′tor n.

pol·li·na·tion

(pŏl′ə-nā′shən)
The process by which plant pollen is transferred from the male reproductive organs to the female reproductive organs to form seeds. In flowering plants, pollen is transferred from the anther to the stigma, often by the wind or by insects. In cone-bearing plants, male cones release pollen that is usually borne by the wind to the ovules of female cones.

pollinate verb
Did You Know? When a pollen grain lands on or is carried to the receptive tissue of a pistil known as the stigma, the flower has been pollinated. But this is only the first step in a complicated process that, if successful, leads to fertilization. The pollen grain contains two nuclei—a generative nucleus and a tube nucleus. The generative nucleus divides in two to form two sperm nuclei. The tube nucleus grows down into the pistil until it reaches one of the ovules contained in the ovary. The two sperm nuclei travel down the tube and enter the ovule. There, one sperm nucleus unites with the egg nucleus, fertilizing the egg. The other sperm nucleus combines with two other nuclei that exist in the ovule. The fused nuclei then develop into the endocarp, the tissue that feeds the embryo. The ovule itself develops into a seed that is contained in the flower's ovary (which we know as a fruit). In conifers, the ovule is exposed (that is, not contained in an ovary), and the pollen produced by male cones lands directly on the ovule in female cones. Fertilization in conifers is not as quick as in flowering plants—the pollen nuclei often take as long as a year to reach the ovule.

In flowering plants, the transfer of pollen from anther to stigma.

Thus we not only hypothesize the presence of proteins in Ephedra pollinations drops, but we also expect that such degenerative processes in Ephedra at the time of pollination drop formation would influence the type of proteins present, such as protein breakdown products that accompany tissue death.
Gymnosperm pollination drops are involved at some point in the capture and delivery of pollen into ovules, followed by pollen germination and fertilization (Gelbart & von Aderkas, 2002).
Floral density has a strong influence on frequency of floral visitors and, thus, also on frequency of successful pollinations (e.
Longevity of flowers may be influenced by timing of pollination, mating system, and growth form (Devlin and Stephenson, 1984; primack, 1985; stratton, 1989; schoen and Ashman, 1995; clayton and Aizen, 1996).

Whether and to what extent individual species form asexual clones has important consequences on milkweed reproductive biology studies since self pollinations among wholly or partially self-incompatible clones may affect levels of fruit set.
Test samples consisted of 30 self pollinations and 30 cross pollinations.
Consequently, hand-mediated pollinations of flowers typically produced more fruits than did the true pollinators of orchid populations in situ (see Tremblay et al.
The recent bicentennial of Charles Darwin's birthday (2009) should remind all plant conservationists that the modern study of orchid pollination begins with Darwin's two editions of a book that concentrated on the role of adaptive floral morphology in the evolution of orchid flowers (Darwin 1862, 1877).
carneus is able to achieve high rates of successful pollination.
However, as future studies address the phylogeny and reproductive biology of Abronieae, it will be of interest to see whether the apparent lability in mating system is evidenced at fine taxonomic levels, and to investigate correlations with life history, habitat, and pollination ecology.
