It's a good question. Maybe some luck posting it at our sister site here: http://www.theeasygarden.com/ ?
Your seeds will grow... depending on the type of apple, you may or may not get the same kind of tree. You don't need to dry the seeds either.... just plant them. Same goes for oranges....
An after thought - don't eat the apple seeds.. a few won't hurt you, but if you store up a handful and eat them all at once you can get quite ill. Just a thought in case you didn't already know that
