(PhysOrg.com) -- A team of scientists in New Zealand has found the local disappearance of pollinating birds over a hundred years ago is having a detrimental effect on the species they pollinated.
(PhysOrg.com) -- A beautifully preserved fossil identified as being of an early relative of the Asteraceae, or aster, family nearly 50 million years old suggests the plant family, which has now colonized much of the planet, ...
(PhysOrg.com) -- Honey bee numbers have been declining almost everywhere due to a pesticide-resistant mite called Varroa. Now a beekeeper in Britain claims to have discovered a strain of bee that destroys the parasite through ...
Pollination is the process by which pollen is transferred in plants, thereby enabling fertilisation and sexual reproduction. Pollen grains transport the male gametes (sperm) to where the female gamete(s) are contained within the carpel; in gymnosperms the pollen is directly applied to the ovule itself. The receptive part of the carpel is called a stigma in the flowers of angiosperms. The receptive part of the gymnosperm ovule is called the micropyle. Pollination is a necessary step in the reproduction of flowering plants, resulting in the production of offspring that are genetically diverse.
The study of pollination brings together many disciplines, such as botany, horticulture, entomology, and ecology. The pollination process as an interaction between flower and vector was first addressed in the 18th century by Christian Konrad Sprengel. It is important in horticulture and agriculture, because fruiting is dependent on fertilisation, which is the end result of pollination.
