Removal of pollinia from pod parent

[Jmbaum]

I apologize if this has been covered anywhere, but searches have yielded no explicit answers.

Is it better to leave pollinia attached to pod parent after it has been pollinated?

I’m aware that the flower collapses within a few day of the removal. Both scenarios can and do occur in in-situ, and certainly both yield seed. From those experienced in propitiation, what is your preferred process? Have we seen any comparative studies? I’m not sure if there is more than a singular trigger for the auxin/ethylene signaling for ovule development. Basically is the pollination the trigger, removal of pollinia from pod parent, or both yield higher viable seed?
