How do seedless fruits make more fruits?

Asked by JLeslie (65417points) August 30th, 2009

If there are no seeds there is nothing to plant to create more fruit plants? Are all seedless fruits genetically engineered by us? How does all of this work?

Some plants reproduce vegetatively. This means they send out runners or “pups” which will grow into new plants. Other plants will have parts such as leaves or stems which, if they fall off the mother plant, will produce adventitious roots and grow into a new plant. The drawback to this vegetative reproduction is that it is the same as cloning and it does not result in any genetic diversity (in some specialized niches this may be an advantage).

Same way other fruits do – with the help of a doctor.

Adoption.

@pdworkin makes sense, of course I have plants in my garden that have pups, I should have thought of that. I am aware that governments have storage facilities with seeds of a large variety of plants in case there is a significant natural occurance that obliterates crops, so does that mean that these plants that don’t have seeds are more vulnerable cease to exist?

How odd. About an hour ago, I was in the kitchen chopping a tomato, and thinking about seedless grapes. I was wondering what other plants are seedless, and how they got to be that way.

To Bio class we go!
Some seedless fruits, such as navel orange and seedless watermelon, do not
reproduce naturally so depend on humans to propagate them. Navel orange and
most fruit trees are usually grafted. Triploid seedless watermelon is grown
from seed obtained by crossing a diploid seeded parent with a seeded tetraploid
parent.
Other types of seedless fruits, such as bananas and pineapple, have natural
vegetative methods to propagate themselves. Bananas and pineapple reproduce by
suckers. The top of a pineapple fruit or crown will also root and form a new
plant.
Some types of seedless fruit, such as persimmon, seedless cucumber, and
pineapple are not always seedless so can reproduce by seed. Persimmon trees are
either male or female. A female persimmon that is not pollinated may produce
seedless fruit but it can produce seeded fruit when pollinated. Pineapple and
seedless cucumber can produce seeded fruit if cross-pollinated, so commercial
growers do not allow cross-pollination. ‘Bartlett’ pears normally have seeds,
but in California’s Sacramento Valley, they often are seedless because of the
favorable climate.

@teh_kvlt_liberal amazing how complex and varied it is. So some fruits that we eat are completely dependent on us to propagate, and I guess we originaly engineered these? Or, does nature sometimes bring them together, but they just can’t reproduce?

I find the pineapple very interesting, I did not know that. I can just lay the top in the ground and I will get pineapple plants?

Well I guess, because that’s the only they can reproduce as far as I know. And to answer your question about the Pineapples, you can’t just cut off the top and leave it there. You must leave some of the fruit in the top and leave it out to dry in the sun until it’s hardened enough. Then you can just plant it and leave it there.

Here’s an interesting story about why bananas are in danger because of that very problem.

Not all bananas, of course – only the ones that Westerners are used to eating.

@JLeslie – Thank you for asking this question! I’ve wondered this myself. Sadly, biology class in my high school was so horrific that I dropped it halfway through the year. So, I’m happy to fill in some gaps here at Fluther!

@teh_kvlt_liberal I’m so glad you received all of that lurve on my question :)
