How can there be seedless grapes? How can they reproduce?

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.

Comes something about seedless watermelon:

Where Do Seedless Watermelons Come From?

This article is excerpted from "Seedless Watermelon Production" by Jerry Parsons, Larry Stein, Tom Longbrake, Sam Cotner, and Jerral Johnson, published by the Texas Agricultural Extension Service.

The seedless watermelon is now a reality.
Seedless watermelons--sweet inside but without the numerous seeds found in conventional watermelons--are the ultimate in convenience foods.

Seed Production.
The obvious question asked about growing seedless watermelons is: "How does one obtain seed of a seedless watermelon?" Obviously, you cannot save seed from a seedless watermelon. So, where do the seeds come from? Simply stated, the number of chromosomes (the threadlike bodies within cells that contain the inheritance units called genes) in a normal watermelon plant is doubled by the use of the chemical colchicine. Doubling a normal (diploid) watermelon results in a tetraploid plant (one having four sets of chromosomes). When the tetraploid plant is bred back, or pollinated, by a diploid or normal plant, the resulting seed produces a triploid plant that is basically a "mule" of the plant kingdom, and it produces seedless watermelons. Seed of seedless varieties are available from most major seed companies.

General Climatic Requirements.
Seedless watermelons are a warm-season crop, preferring relatively high temperatures for optimum growth. Daytime temperatures of 80 to 95 degrees F. and night temperatures of 60 to 70 degrees F. are best. When temperatures are lower, plant growth is slowed considerably. With favorable weather, seeded fields can produce ripe fruit in 85 to 100 days.

Planting.
Poor seed germination is the main problem with growing seedless watermelons. When direct seeding, the soil temperature should be minimum of 70 degrees F. at a depth of 4 inches. Soil temperatures below 70 degree F. will reduce germination and emergence. When growing transplants, use 12- to 2-inch seedling cells or peat pellets. Soak the planting medium thoroughly, and let drain 4 to 6 hours before sowing. Plant 1 or 2 seeds per cell or pellet. The greenhouse temperature should be 75 to 85 degrees F. during the germination period. Do not allow the growing medium to become dry, but do not over water during initial germination. Begin watering, as needed, after 10 to 15 percent of the seedlings have emerged. Plants should be ready for transplanting in 3 to 4 weeks. Transplants should have not more than 3 true leaves when set in the field. Use of older, larger transplants can cause slow, stunted growth and poor yields. In-row and between-row spacing is generally 48 X 80 inches.


Pollination.
The male and female flowers are born separately on the watermelon plant. Female flowers must be pollinated for fruit to set. Also, cross pollination must occur between a seedless and a regular type watermelon for seedless fruit to be produced. This is best accomplished by planting a standard watermelon variety in the garden. Approximately one-third of the plants in the garden should be of the standard or 'pollinator' variety. Honey bees are the principal insects that pollinate watermelons. Pollination is a must, and poor or partial pollination may result in misshapen fruit and no seedless melons.

Harvesting.
The lower side or 'ground spot' of the fruit should be cream-colored or yellowish. Thump fruit to check for ripeness. The result will vary. Generally, a solid sound indicates ripeness, while a sharp echoing sound indicates a greener fruit. The tendril or 'tail' which occurs in the axils of leaves (where the leaf attaches to the vine) along the stem can be used as an indicator of ripeness. Experienced harvesters say that if the 2 tendrils nearest the fruit are dry, the seedless watermelon is ripe. It is important to note that the first few mature melons in the garden may frequently contain small seeds. This condition is most prevalent under stressed conditions, such as low soil moisture, insufficient fertilizer, temperature extremes, or disease pressure, which affect normal plant development.

Each planting of seedless watermelons actually produces 3 different types of watermelons -- the regular seeded watermelons (from pollinator plants), the true seedless melons, and a light-green tetraploid melon that produces a very limited number of seeds, from which next year's planting can be made.

I honestly don't know. I do know that they should start growing some seedless men!

Genetic mutation

They are hybrids....They have seeds only very very small and immature...
Peace.

its called selective breeding

With Invisible seeds, of course...What else!

It'd be utterly miraculous if bunches of juicy red and green Grapes were discovered to be growing their own crops, or, if giant It will watermelons began popping out of a Magician's magic hat, putting the traditional (and suspiciously elusive...) Rabbit out of the job. I'd like to see that though...

Lets face it...that Bunny is not at all a reliable form of entertainment is it? We want to see some action, not hear a bunch of empty white lies, or hear the same old fictitious fantasy phenomena again and again...

Rabbits are so last season too. Seedless on the other hand, is entertaining, AND edible!!! Yummo...Multi-talented little guys/gal's aren't they?

I mean, lets face it, we're not exactly Children here either...waiting in vain, year after year, for Santa to slide down the chimney on Christmas Eve...not gonna happen. That soot will not get that much needed and ever promised clean, courtesy of Santa's big, furry red cloak any time soon.

OK Clo, here's the deal. You can ONLY get them from the Giant, if you want to see it for yourself (well, not actually SEE them of course) They ARE invisible after all...

Alternatively, you could grow your own invisible Vineyard, and make invisible Wine to sell to under-age Teens on the black market . Hmm...good idea actually, if I do say so myself! Lucrative too. If it works, I'll be your Business partner if you like! We'll be rich - and a little tipsy too!

Secretly, I am now hoping the Seedless Fruit (not the Giant's beans, the escapees...the ones that got away...you know like the ones Jack used to have) are reading this, and get inspired to relocate, get out of the house, and become Career-Fruits.

That Giant is very controlling though...but, you could rescue them Clo! Just ask Jack for directions. It's really easy to get lost on a giant Bean stork, with all that cloud cover to

FEE-FIE-FOE-FUM. I smell the blood of an English-man...STOMP, Stomp, Stomp. Or something similar along those lines. If you hear this, don't run, slide down that stork without hesitation! IMMEDIATELY.

You see, he's a perpetual Insomniac, BUT, on the odd occasion, his beloved Watch-Chicken Chester, is the only one who can wake him from his snoring, roaring slumber.

If you're unlucky enough to avert his "Guard - Hen's" beady, watchful eye, you will find a handful of genuine Invisible Magic Beans, stashed in a glimmering Gold, draw-string pouch (this IS visible, and IS as genuine as the beans inside it). It is tucked securely under the Giants Gigantic four-poster bed, inside the mouse-hole located on the left-hand side.

You will require three things to successfully complete the mission, and come away with the Seeds. For this quest to be a success you'll need---

1* Courage

2 * A thirst for knowledge and most importantly,

3 * A nice sturdy butt (you may need one if you are forced to take a slide down the Stork...Doesn't look as inviting as a leisurely trip down a water-slide, put it that way...A better option than the alternative though, I guess.

GOOD-LUCK on your mission Clo. My thoughts will be with you, as you attempt to uncover the proof we all need, to solve this age-old mystery, once and for all...

The "Seedless" Fruit Phenomenon... A worthy mission, if ever their was one.

Be safe -
---Luv Gracie (-:

they stick a small syringe in them and suck all the seeds out before they sell them .its alot of work....lol
