Re: [nafex] self fertile pears?

The purpose of a plant seems to be to reproduce itself.

I have heard that some plants "get frustrated" after years of not producing seed and "fix" the problem.

We are not allowed to grow the "sterile" forms of the invasive buckthorn here in Minnesota because they tend to revert to seed production when they get "old."

Some isolated "female" dioecious plants will grow a branch of "male" flowers so as to be able to make viable seeds.

I don't know what the pears might be doing to pull this off.

"Apparently I should have
mentioned...................The isolated pear
tree out in the countryside produces viable seed."

So so you believe the tree to be self fertile?  That is
something I've not
heard of but I certainly consider it possible.  When
isolated pear trees
have born fruit here, I never have even checked their seeds
so I really am
only speaking from the literature.
