There is no soft mast crop (fruit) that deer will not attack. Sometimes they will ignore it until it has frozen from the first hard frost of the year, like with crab apples. Some they will pick from trees if they smell they are ripe, like commercial apples. Some they will wait until they fall, like persimmons and pears. Because they are not ripe until they drop.
The bad thing about soft mast is that it is usually consumed before hunting season opens. However if the trees were particularly heavy with fruit, deer remember this and will come back and check to see if anymore are available. Especially after the first good snow fall of the year. They will be trying to put on all the fat they can before Winter really grips the land.
