How are oranges and grapes with no seeds and pips grown?

Answer 1

They cross pollinate vines of grapes that have minimal seeds intil they get a vine that produces seedless grapes, then they cut parts of the vine and graft them onto other vines.

~~~~~~~~~~~~~~~~~~~~~~~~

Grape breeders create new seedless plants by placing the pollen of a seedless grape onto the flowers of a grape variety that has seeds. They then cut open and inspect the fruit of every single plant that grows from this match. The breeders are looking for seeds -- some plants will have seeds in their fruit and others won't.

When they find a plant that has no seeds, or maybe just has very tiny traces of seeds that you wouldn't be able to taste, the grape breeders use it to make more seedless plants. One way is to cut off small pieces of the seedless plant's vine and place it in special growing conditions in a greenhouse. Eventually, the pieces of vine will grow roots and become new, individual plants. This technique is called propagation.

Or, the breeders can graft, or attach, a piece of the seedless grape variety onto a healthy vine base, called a rootstock. Think of it like this: When someone cuts their hand, a doctor sews the cut together, and the two pieces heal as one. The grafted vines grow together the same way. And, the grape variety attached to the rootstock keeps producing delicious seedless grapes.

Answer 2

Most citrus are grafted on to rootstock. Grapes can be rooted from cuttings. They are most probably grown from seeds that are the product of cross pollination, then selected for their taste and lack of seeds. Then they can be grafted or rooted.

Answer 3

All seedless frut are made from cuttings, which then are cut again into another plant. The same way they get tangelos and tangereens. Grafting creates mixes of plants. Check out Howstuffworks.com

Answer 4

Genetic Engineering. The genes which codes for the pips are removed.

Answer 5

they choose an countless quantity of hay (Timothy, Orchard, Bluegrass) daily to boot as clean water daily. additionally they choose a good fortfied pellet w/out each and every of the crappy colored products in it. and that they choose a good form of vegetables. some good vegetables are lettuces (no iceberg-it may reason diarrhea) like crimson lettuce, green leaf lettuce, romaine lettuce; green/crimson/yellow peppers, cilantro, cucumber, grape tomatoes, toddler carrots, vegetables (like collard or mustard), parsley, celery (decrease up into very small products), and apple (a million-2x consistent with day). i wish this enables. you may get greater advice from those supplies Guinea Pig Cages and Guinea Lynx. good success!

Answer 6

There are plant engineers who alter the genetics of the plants to make them grow that way

Answer 7

I bought mine from Stark Bros, They have some really good deals and plants thrive real well

Answer 8

They aren't seedless really, they just have very small/soft seeds that we don't mind eating :)
