Default Question on self-incompatable flowers

This info was taught to me by my mentor Monika Gottschalk a world
renowned breeder of brugmansia.

You can visit her site http://www.monika-gottschalk.de/

She is a very kind and generous person and will surely answer your
questions. It is getting close to her busy season but for now she is
snowed in and should be able to answer you.

Cheers from here ,

I have found several sites which mention how a flower stops it's own pollen
from fertilizing it, but none mention if this same flower can accept pollen
from a compatible plant while holding back it's own pollen.

In other words, if pollinated with it's own pollen, will the bloom die, or
is it still accepting of a 2nd pollen? Solanaceae is the family in
question, Brugmansia specifically.

Rumor has it that the breeding potential of the bloom is ruined if self
pollinated, and yet the pistil is often located among or behind the pollen
bearing anthers, which is a very poor design if this is the case. I don't
think nature would be so careless, but .....?

Brugmansia will only accept the first pollination.
This is why great care must be taken while harvesting pollen bearing
anthers if you intend to use the same flower as a pod parent.

No disrespect intended to the poster, but I am looking for something more
substantial than a statement?

Can anyone please direct me to a reputable (scientific) site where
information on this general topic can be found? (Not one of the collectors
groups please; Fanciers groups are indeed pleasant and useful in many ways,
but have the occasional tendency to accept un substantiated claims as
botanical fact).
