HOW DO SEEDLESS GRAPES REPRODUCE?
(http://www.chow.com/stories/10692) Most seedless fruit comes about the same way as other fruits, which commonly are grown from cuttings or grafts and not seeds. To make a cutting, a branch or vine is cut from a plant, fed a nutrient mixture, and put in dirt, where leaves and roots form. In a graft, the branch, vine, or bud is grown right into another plant’s trunk or rootstalk. With the exception of seedless watermelons, which have a complicated propagation method, seedless fruit can’t reproduce on its own—it must be grafted each time. Seedless fruit originated from genetic mutations that humans discovered and cultivated. For example, seedless navel oranges date back to the 19th century and a single mutant tree in Brazil, whose progeny all come from buds grafted onto other citrus trees. Scientists are working continually to produce new varieties of seedless fruit, either by breeding different varieties together or by stimulating genetic mutations. In recent years, they have created so
