pollinating when pollen is not accepted

As the Paramongia weberbaurii is almost flowering, was trying to work 
out how to get pollen accepted.  Was given the name of Christopher Ong 
in Australia to ask.  His answer is:

The idea is to stimulate the ‘pistil’ into accepting potential growing 
pollen tube. This is quite extraordinary in the plant world. For 
example, we use to mixed in ‘hibiscus’ pollen with other pollen and just 
use that without even microwaving or killing the hibiscus pollen first 
as we know that hibiscus is not compactible with the plant we are trying 
to pollinate but somehow stimulate the pistil to accept the pollen from 
like compatible plants.

In your case I would suggest using Permianthe peruviana pollen if 
available. Microwave these pollens for around 1 to 2 minutes to kill 
them. Let it cool for a minute and then mix that with the Paramongaia 
pollen before applying.

If you do not have other suitable ones then I would suggest using pollen 
from one plant onto the other. Don’t worry about it being of the same 
clone (that cannot be help) but treat the component parts as suggested 
below first.

Collect the pollens and then treat then with a dash of diluted nectar 
from other flowers. Leave it for about half an hour and then apply with 
a brush. What happen here is that the pollen is already stimulated and 
the pollen tube may start to grow and develop. Some people also brush 
the stigma with the same solution about 5 minutes prior to application 
of the pollen.

Such techniques are very subjective and may not work all the time. We 
had plants that worked one year and not the next. I would suggest doing 
the pollination in the early morning or evening when the plants should 
be more receptive.

So it is not foolproof, but worth a try.

As I had looked over the years how to do this, at least this is from 
someone who has used this method and sometimes it has worked.
