Pollination
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.

Bees are important, the argument goes, because they flit about from flower to flower, picking up pollen from one plant and inadvertently depositing it on another. In other words, they facilitate plant sex. And plant sex is how you get fruits and nuts…lots of the tasty things we humans like to...

Abstract, Proceedings of the Royal Society B / Biological Sciences, 2014 Pollinators contribute around 10% of the economic value of crop production globally, but the contribution of these pollinators to human nutrition is potentially much higher. Crops vary in the degree to which they benefit...

Abstract, Proceedings of the Royal Society B / Biological Sciences, 2007 The extent of our reliance on animal pollination for world crop production for human food has not previously been evaluated and the previous estimates for countries or continents have seldom used primary data. In this...

Many flowers are pollinated without the aid of animals (insect, bird, or mammal). Some are pollinated as the currents of wind or water act as vectors. These flowers do not generally attractanimalpollinators. Most conifers and about 12% of the world’s flowering plants are wind-pollinated. Wind...

Abstract, Biodiversity Science, 2017 The transfer of pollen in most seed plants relies on diverse pollination vectors. In comparison with animal pollination (zoophily), wind pollination (anemophily) has long been regarded as an inefficient mode and thus has received relatively little attention....

Abstract, Insect Conservation and Diversity, 2017 Current research, management and outreach programmes relevant to insect pollinator conservation are strongly focused on relationships between pollinators and insect‐pollinated crops and wild plants. Pollinators also visit wind‐pollinated plants to...

Pollination occurs when pollen grains move from anthers to a reproductively mature stigma. After pollen lands on the stigma, it initiates pollen tube formation. Pollen tubes are channels which grow down the length of the style to the ovules. After a pollen grain travels down a pollen tube it...

This bulletin, based on contributions from various contributors and edited by Dr. D.W. Roubik, introduces the reader to various aspects of natural and insect pollination. It discusses the pollinators themselves, and the ecological and economic importance of pollination, as well as applied...

14 កក្កដា 2015 In northern Thailand, widespread mono-cropping has led to environmental changes which have affected the natural habitat of bees, resulting in diminishing numbers and reduced honey production. As ECHO Asia already has a variety of different flower species, trialing honey production seemed like a...

20 មករា 2015 Sorghum is primarily self-pollinated, meaning that a sorghum plant will accept pollen from its own flowers. Sorghum can also accept pollen from other sorghum plants (cross-pollination) by means of wind or insect transfer. Cultivated sorghum is generally cross-pollinated between 2 and 10%, with...

19 មករា 1976 Worldwide, more than 3,000 plant species have been used as food, only 300 of which are now widely grown, and only 12 of which furnish nearly 90 percent of the world's food. These 12 include the grains: rice, wheat, maize (corn), sorghums, millets, rye, and barley, and potatoes, sweet potatoes,...

Anemophily is the process when pollen is transported by air currents from one individual plant to another. About 12% of the world’s flowering plants are wind-pollinated, including grasses and cereal crops, many trees, and the infamous allergenic ragweeds. Wind pollinating plants release billions...

Abstract, Scientific Reporst, 2017 Mutualistic biotic interactions as among flowering plants and their animal pollinators are a key component of biodiversity. Pollination, especially by insects, is a key element in ecosystem functioning, and hence constitutes an ecosystem service of global...

20 មករា 2007 Hand pollination of atemoya flowers is a simple procedure based on the interesting fact that the female and male parts (Figure 1) of each flower mature at different times.

Pollinators are an element ofcrop associated biodiversity, and provide an essential ecosystem service to both natural and agricultural ecosystems. In the case of agricultural ecosystems, pollinators and pollination can be managed ("planned" crop associated biodiversity) to maximize or improve...
- Hand-pollination is a technique used by seed savers to ensure that plants produce seed that is true-to-type and that flowers are not contaminated by the pollen from another variety. The process varies among species, but with plants that produce unisexual flowers like corn, the uncontaminated...

Not all edible crops need to be pollinated by bugs. Some don’t need bees, or other pollinators, at all; and some benefit from them but can still produce even if they are not around.

19 កក្កដា 1999 In Honduras, after Hurricane Mitch, several NGO's working with small farmers were concerned that cross-pollination occurring between the hybrid maize variety and existing open-pollinated varieties would reduce yields of both traditional varieties and the new, improved open-pollinated varieties in...

20 តុលា 2014 The ECHO Florida Seed Bank offers a wide variety of useful crops, many of which naturally attract pollinators (Fig. 3). Encouraging beneficial insects in your garden is a key component in promoting biodiversity, controlling unwanted pests and increasing pollination of your crops. If you live in...

20 តុលា 2014 Worldwide, the number of insect pollinators has declined sharply in recent years. Beekeepers have experienced heavy loss of honey bee colonies; in the United States, the number of managed colonies is half of what it was sixty or seventy years ago (USDA). The number of wild pollinators has also...
