text: Some seedless fruits are grown from grafts on existing trees.   Seedless grapes are not technically seedless, although they are seedless for practical purposes. Seedless grapes are different than most seedless fruits because the seeds initially develop but abort when they are very tiny embryos. So,  in seedless grapes, normal fertilization does occur. You can often see \nthe remains of the aborted seed in the mature fruit. Seedless grape breeders can remove the tiny embryos before they abort and grow them in tissue culture to produce a mature plant. This is termed embryo rescue.
