Why Does My Seedless Watermelon Have Seeds

Seedless watermelons are known in the trade as triploid watermelons; they contain three sets of chromosomes. Plant breeders obtain seeds for these melons as the result of crossing a melon that has double chromosomes with a regular watermelon. This is done by hand pollination.

Why are there still seeds in seedless watermelon?

Seedless watermelons were invented over 50 years ago, and they have few or no seeds. Watermelon breeders discovered that crossing a diploid plant (bearing the standard two sets of chromosomes) with a tetraploid plant (having four sets of chromosomes) results in a fruit that produces a triploid seed.

Why are there black seeds in my seedless watermelon?

The answer is “No.” Well, in his opinion, 99.99 percent of the time it’s “No.” The errant black seed that is sometimes found in a seedless watermelon is actually an empty seed coat that sometimes turns from white to black when stress — which can be environmental or chemical — is placed on the plant.

Can you eat the seeds in seedless watermelon?

Watermelon has two kinds of seeds: black and white seeds. When you get a “seedless” watermelon, they’re not actually seedless because the white seeds are in it. The white seeds are also in non-seedless watermelons. So, these are totally safe to eat, and they’d be a hassle to remove.

What are the seeds in a seedless watermelon?

This triploid seed is the seed that produces seedless watermelons! In other words, a seedless watermelon is a sterile hybrid which is created by crossing male pollen for a watermelon, containing 22 chromosomes per cell, with a female watermelon flower with 44 chromosomes per cell.

Will seeds from a seedless watermelon sprout?

Early seedless varieties did not have the sugar and flavor levels of seeded types, but plant breeders have improved these traits and new varieties no longer have these problems. However, one problem that does continue is seed germination. Initially, seed germination of seedless watermelon was quite low.

How do seedless watermelons propagate?

Seedless watermelons are particularly interesting because they must be propagated by seed, and yet growers can still exploit parthenocarpy. As in the case of bananas, triploid watermelons cannot produce functional seed, but they still develop good fruit through parthenocarpy.

Why are my watermelon seeds brown?

I. Too much phosphorus compound in fertilizer may also induce the empty brown seeds to develop. It is common for small, white and soft seeds to develop in triploid varieties. When you grow seedless watermelon, expect a few seeds to form.

What happens if you swallow watermelon seeds?

It may come as no surprise that despite what we were told as children, swallowing a watermelon seed will not cause a watermelon to grow in your stomach. They basically just move through your digestive tract without being digested, similar to what happens when you swallow a piece of gum.

How do you know if a watermelon is bad?

The easiest way to tell is to check the skin for any soggy spots and patches of greenish-blue, black, or white mold. Even if the exterior looks OK, there’s a chance that the fruit could have gone bad. If the flesh has noticeable dark spots or is covered in anything slimey, you should toss it.

Is seedless watermelon healthy?

The flesh of the fruit (and the rind for that matter) is also nutritious, so both seeded and seedless still have great health benefits. Watermelon is a good source of potassium and is 91% water making it great for hydration. Seedless watermelon is not a genetically modified food; it is a result of cross-breeding.

Do watermelon seeds have cyanide?

While watermelon seeds are safe and beneficial to eat, the seeds of cherries, peaches, plums, apples, and apricots all have cyanogenic compounds in them. The good news is, a 2015 review out of the University of Leeds suggested a person would have to consume between 83 and 500 apple seeds to get acute cyanide poisoning.

Are watermelons true to seed?

Watermelons are grown from seed. You may be tempted to use seed out of a melon you bought, but don’t waste your time. You would end up growing what we call pig melons: A melon variety that’s only good for feeding to the pigs. Buy your seed, and if possible buy an open pollinated heirloom variety.

What are the white seeds in watermelon?

White seeds are really just immature black seeds. They’re soft and almost translucent because they are only just beginning to grow and develop. The seeds are infertile, so they won’t sprout into a watermelon plant if you planted them. They are, however, so soft that they aren’t a bother to swallow along with the flesh.

How do you grow seedless watermelons if they have no seeds?

Seedless watermelons are triploid. They have three sets of chromosomes. This odd number results in them being sterile and not producing seeds. The way they become triploid is by mating a diploid male with a tetraploid female.

Can you plant the white seeds from a watermelon?

The white seeds cannot be used to plant and grow a watermelon plant, as they are infertile, but both types of seeds are edible.

Are seedless fruits GMO?

Seedless plants are not common, but they do exist naturally or can be manipulated by plant breeders without using genetic engineering techniques. No current seedless plants are genetically modified organisms (GMOs). All seedless fruit fall under a general category called parthenocarpy.

What is the difference between seeded and seedless watermelon?

The difference between the two is that while traditional, seeded watermelon contains hard black seeds, seedless watermelon has been bred to produce very soft and pliant edible seeds.
