Pollination
-By Jay Glaus
The Structure Of A Flower
The flower’s main purpose on a plant is for reproduction.
The Parts Of A Flower… Pedicel
Pedicel – The Stalk Supporting The Flower.(a.k.a. Stem)
The Parts Of A Flower… Receptacle
Receptacle – The Part Of The Flower To Which The Others Are Attached
The Parts Of A Flower… Sepal
Sepal – Each Parts Of The Calyx Of The Flower
The Parts Of A Flower… Petal
Petal – Each Parts Of The Corolla Of A Flower.
The Parts Of A Flower… Filament
Filament – Male Reproductive Organ Of A Flower.
The Parts Of A Flower… Anther
Anther – Part Of The Stamen That Produces The Pollen.
The Parts Of A Flower… Stigma
Stigma – Part Of The Pistil That Receives The Pollen.
The Parts Of A Flower… Style
Style – Central Part Of The Pistil.
The Parts Of A Flower… Ovary
Ovary – Lower Part Of The Pistil Which Produces Eggs.
The Parts Of A Flower… Pistil
Pistil – The Set Of Female Parts Of A Flower.( Stigma, Style, Ovary )
Pollination (Typical Method)
A bee is attracted to a flower from color, aroma, or sweet nectars. As the bee sucks up the nectar, pollen from the anther(s) gets stuck on to the bee’s body/fur.
Pollination (Typical Method)
Pollen from the Anthers gets stuck to the Bee’s body
Pollination (Typical Method) When the bee moves on to
the next flower, some pollen that was stuck to the bee from previous flowers falls off and onto the stigma of the new flower.
Basic Flower
Pollination (Typical Method)
The Bee leaves to go to other flowers. In the meantime, the pollen left on the stigma produces a tunnel down to the ovule to pollinate it.
Pollination (Typical Method)
The flower withers or wilts. Ovules grow and grow and produce seeds. The ovary fattens to become a fruit.
Other Methods of PollinationProcess is still the same, but pollen has different carriers.
Although Bees are the main insect
carrier, pollen can stick to other insects
as well including: Butterflies, Ants,
some Beetles, and even Birds
When wind blows, pollen is picked up with the wind and can be carried to
other flowers. Pines produce
great amounts of pollen and often use this method.
Self pollination occurs when pollen falls onto
its own stigma.
Other Methods Of Pollination
Water Pollination
Occurs mainly with plants growing on water. Pollen uses water as medium for transportation.
Pollination By Q~Tip
Indoor plants, where there are no insects may use Q~Tips to pollinate the flowers. The cotton from the Q~Tip carries the pollen like a bee’s fur. Some people use dead bees on a toothpick or stick.
(cotton swabs)
Cross - PollinationCross Pollination occurs when pollen from one kind of flower is deposited onto a different kind of flower. The genes from the two
flowers can blend, and the flower resulting from the seed produced can be a mix. Cross Pollination
can also be used with fruits to mix flavors.
Grape Farmers keep their grape bushes a certain distance away
from each other to keep from cross pollinating.
Cross Pollinated Fruit
Pluots… Half Plum, Half Apricot
Developed In Late 20th Century by Floyd Zaiger in the
USA.
Want To Try Cross Pollinating? Here’s How…
Would you like to try to grow a new kind of fruit? Here’s how using cross pollination. If you take an apple tree and a plum tree, for example. When they flower, with a cotton swab, pollinate some flowers on the apple
tree, then using the same cotton swab, pollinate the plum tree. When the flower turns into the fruit on either tree, plant it.
The resulting fruit will grow on the tree that grows from your planted fruit.
So, what happens if flowers aren’t pollinated?
Some flowers do not get pollinated, since there are so many. They simply wilt and fall off of the plant. It does not harm the plant any, just no seeds are produced. As you may know, we are undergoing a small shortage of bees at the moment. Cotton Swab pollination may become more widely used in farms as well if the shortage continues.
