As with vegetative propagation, the advantages of self-pollination are that if the plant is very well-adapted to a specific location, those genes are maintained. In this case, the interdependence between species is shown to be tenuous at best. Hand pollination is used to improve crop yields, avoid cross-pollination, and to create hybrid crops. Northern Woodlands All rights reserved | site by, . It is commonly grown for cattle feed and, in particular, as hay for horses.

Pollination by insects is a part of Unit 6 Reproduction, chapter 2 Sexual Reproduction in Flowering Plants and carries a total of 4 to 5 marks. Attracting insects that might carry pollen from one tree to another tends to facilitate an out-crossing mode of reproduction. Pollen is transferred between flowers of the same species in order for seeds to be produced. As logic would have it, species that rely on insects (mostly bees, wasps, flies, beetles, butterflies, and moths), birds, and bats, tend to have fragrant (sometimes stinky), large, or otherwise showy flowers. The stamen produces pollen, which is transferred to the pistil. Most conifers and about 12% of the worlds flowering plants are wind-pollinated. Hurd named the grass "hurd grass" but a farmer named Timothy Hanson began to promote cultivation of it as a hay about 1720, and the grass has been known by its present name since then. It is most common in our temperate deciduous and in boreal forests but extremely uncommon in tropical rain forests.
