pollination's Usage Examples:

The study of the fertilization, or as it is now generally called "pollination," of flowers, was continued by Darwin and taken up by other workers, notably Friedrich Hildebrand, Federico Delpino and the brothers Fritz and Hermann Muller.

Some have the stigma, to which the pollen adheres during pollination, like a little pinhead protruding from the flower.

, or dioecious with staminate and pistillate flowers on different plants, as in willows and poplars, cross pollination only is possible.

As the venue also encompasses club nights, live music events and a vibrant café bar, their audiences benefit from cultural cross-pollination.

It is also probable that the various forms of the angiospermous flower, with its many specialized mechanisms for pollination, may be the result of insect-visits, the flowers becoming adapted to certain kinds of insects, and the insects having undergone corresponding modification.

obviate any possibility of cross-pollination.

For instance, in many flowers the filaments are at first directed outwards so that self-pollination is not possible, but later incline towards the stigmas and pollinate them (e.

Autogamy >>Pollen may be transferred to the stigma of the same flower - self-pollination (or autogamy), or to the stigma of another flower on the same plant or another plant of the same species - crosspollination (or allogamy).

Effective pollination may also occur between flowers of different species, or occasionally, as in the case of several orchids, of different genera - this is known as hybridization.

Muller also suggested a modification of the Knight-Darwin law, which had left unexplained the numerous instances of continued successful self-pollination, and restated it on these terms: "Whenever offspring resulting from crossing comes into serious conflict with offspring resulting from selffertilization, the former is victorious.

The ovule is usually surrounded by one integument, which projects beyond the tip of the nucellus as a wide-open lobed funnel, which at the time of pollination folds inwards, and so assists in bringing the pollen-grains on to the nucellus.
