Botany : How Do Plants Which Bear Seedless Fruit Reproduce

Are they just genetically engineered this way, then cuttings taken, or what? ~~~ itsleemail ~~~

Best Answer To Botany Question

There are several reasons depending on what fruit u are talking about, that produce seedless fruits and propagation are generally by vegetative means, such as cuttings, grafting, tissue culture methods etc. Banana for example is capable of producing fruits without undergoing fertilisation, in the process called parthenogenesis, and no seeds is produced. (Seeds are develop from ovule into embryo, as the results of fertilisation, and ovary will develop into fruits). Banana is propagated by vegetative means, using suckers, that is the plantlet that appears at the base of the mother plant. Tissue culture method is ideal for banana for commercial scale planting Grape can be induced to produce seedless grape using growth hormones such as auxins. They can be propagated by using cuttings. Seedless watermelon is produce by crossing (hybridisation) of diploid (2n) and triploid (3n) parentage. So when paring of chromosome during fertilisation, one of the triploid chromosome have no partner to pair with and this will results in production sterile fruit, . fruit without seeds. Seedless watermelon are propagated by planting the two type of melon, the 2n and 3n type, simultaneously. making sure that they flowers concurrently, so that cross pollination can occurs to produce seedless fruits. It is possible to produce seedless watermelon by cutting, but commercially it is not viable. There are also naturally occurring sterile (seedless) fruit after undergoing mutation, such as some guava cultivars. However, once the branches of the fruit tree is found to be producing seedless fruit, vegetative propagation from this mutated branches will produce clone of seedless fruits. Exposing seeds with mutagenic rays such as gamma rays to some seeds may also results in producing seedless fruits, when the exposed seeds were planted and growed to maturity.

All Answer To Botany Questions

Answer 1

Normally the Flowers before the fruit will have seeds, or it will drop some sort of spore through another way.

Answer 2

I would guess by being pollunated by bees.

Answer 3

God only knows...he create these plants and everything else so the mystery is up to him

Answer 4

they reproduce asexually, basically they clone themeselves, every new plant is identical to its parent

Answer 5

They cannot reproduce by traditional means. The plant which bears seedless fruit is cut and grafted onto another normal plant. Once it has been attached to the other plant it can continue to grow and bear seedless fruits.

Answer 6

IDK i was hoping to read some answers. Interesting question

Answer 7

Thats the beauty of nature, we cannot create life because we are not in control but we can modify.

Answer 8

Yes, these plants were genetically engineered to produce seedless fruit. Youre right: cuttings are taken and planted to propagate--they make clone plants in other words/or seedless fruit are put onto other plants, where they grow.

Answer 9

Many of them are hybrids. Mules, for example, dont reproduce, but if you cross a donkey with a horse you get a mule every time. Most seedless plants work the same way.

Answer 10

Humans. Seedless watermellons are hybrids of two pure watermellon strains which reproduce normally by seeds. When the two pure strains are crossed, the offspring is sterile. This is the vegetable equivalent of a mule. Some seed bearing plants are reproduced only by cuttings however. French tarragon is one individual plant which has just the right balance of essential oils to make spice. It would probably be impossible to reproduce the cross which resulted in this particular plant and the way it tastes.

Answer 11

it is from the pollen on the flowers before the fruit grows.

Answer 12

Yes, youre on the right track. However, it is important to know what kind of seedless fruit youre talking about. Sometimes, it is possible to take the flowers that form before the fruit and cut them off and dry them. The seeds would be in the center of the flower. For example, if you take regular grass and mow it and then take the clippings and put them on dirt and water them, they grow new grass seedlings. What is your fruit?

Answer 13

Well for seedless grapes I know you cut a piece of the vine and plant that and it will grow into a seedless grape plant. For potatoes you cut the potato into fourths and you plant that and it will grow more potatoes. And I think for other ones your plant the root or something Im not completely sure.

Answer 14

several answers If you go to a grocery store today to buy grapes, there is a good chance that the only type of grape you can buy is seedless. Nearly all grapevines in production today produce seedless grapes. It turns out that most fruits today do not come from seeds. They come from cuttings instead. This is true of grapes, blueberries, apples, cherries, etc. (pretty much all fruits except citrus, although scientists are working on that, too). A piece of a vine or branch is cut off, dipped in rooting hormone and then placed in moist dirt so that roots and leaves form. Because they come from cuttings, new grapevines are essentially clones of the vine they were cut from. Seedless grapes actually do contain seeds at some point. But a genetic error prevents the seeds from forming hard outer coats like normal seeds do. Seedless fruit trees are produced by cuttings, bud grafting and other clonal propagation techniques to ensure the same desirable characteristics of the parent plant is duplicated in the offspring. For this reason, even seeded fruit species are propagated in the same way. What results is a whole orchard of genetically identical trees. Abstract not available for EP1213956 Abstract of corresponding document: WO0117334 The invention provides fruiting plants that produce seedless or sterile fruit. The production of seedless or sterile fruit is the result of genetic modification which prevents or disrupts functional expression of the lt;igt;MdPIlt;/igt; peptide of SEQ ID NO: 2 or a variant thereof, or of the lt;igt;MdAP3lt;/igt; peptide of SEQ ID NO: 4 or a variant thereof, or both.

Answer 15

Many plants have been genetically engineered so that they produce seedless fruit. This although being preferable for human consumption, is however detrimental to the natural reprductive cycle of the plant and would mean that in nature they would die out. All plants producing seedless fruit have had their DNA altered so that new strains of the old seeded versions are produced without the seeds. Horticulturalists who grow these plants know that they will not produce baby plants naturally. Instead new plants are cloned from good strains of the crop so that farmers can rely upon healthy crops with good DNA. The method by which large laboratories produce hundreds of little cloned plants is called tissue culture in which cells from the mother plants are taken using a cotton swab and are grown in perfect conditions resembling those in their natural habitat. This process is carried out on a large scale so that many new plants are produced. Many scientiststs use this method because cloning plants means that the resultant crop has the same benefits as its mother such as high yield, good resistance to rot etc and means that farmers can rely upon consistent high yields. So you can see that plants bearing seedless fruit are unable to regenate themselves alone and man must do it. Some plants which have not suceeded to reproduce well by seed have evolved the ability to layer themselves across the ground so that the branch touching the soil roots over a long period of time. Examples of plants which do this are rhodedendrons. In the wild plants adapt to their surroundings so any existing on the edge of a cliff have evolved so that they rely less on seed reproduction and more on subdividing from the central trunk. This is because any seeds that are produced would be scattered into the sea below. Yuccas have adapted in this way because they exist on cliffs above the sea and is why they rarely flower.

Answer 16

THERE ARE VARIOUS WAYS ONE OF MY FAVORITES IS THE GRAPE VINE WHICH IF A CUTTING IS PLACED IN THE GROUND AND WATERED WILL GROW ROOTS AND MAKE A NEW GRAPE VINE. THERE ARE OTHER WAYS ONE IS TO GROW AN UNWANTED PLANT SUCH AS A CRAB APPLE AND WHEN IT IS ABOUT 3-4 TEARS OLD CUT IT OFF BELOW GROUND LEVEL AND GRAFT A SCION TO IT FROM A GOOD APPLE TREE. THE HARDY ROOT WILL PROVIDE NOURISHMENT FOR THE SCION AND YOU GET A GOOD APPLE TREE. THESE ARE JUST A COUPLE OF MANY.
