   Some weeks ago I asked of you to please explain how a pear tree (Ure) 
can produce fruit without a pollinator.  I wondered if, somehow, it could 
become self-fertile and one of you answered saying that pear trees sometimes 
produce seedless fruit if they bloom on a warm day.
   The tree did bloom on a warmer than average day however all of the 
fruits contain seeds!  The tree is nearly twenty years old and I can't help 
but wonder if a pear tree can become self-fertile if it hasn't produced 
seeds in a great long time.  Is it possible?
