To Julius and others interested in this subject,

See this link for pollination chronolgy and details:


They had to remove indehiscent male flowers and dissect anthers under a 
microscope to acquire pollen early enough to pollinate the females. The male 
flowers that were "ripened" with heat and ethylene exposure appear to be most 
successful, but could it be that this may simply be due to timing? See their 
web page for details, although it was really an amazingly low tech kind of 
operation using film canisters, a pilot light on a kitchen stove, and 
over-ripe apples. It might be interesting to repeat and expand upon this 
experiment in some future Amorphophallus titanum flowering, or possibly in 
some other genera.

The pollination chronology page can also be accessed using the technical 
details link from this before-mentioned page about the seedlings:

<< Yes, thanks for pointing this out.   I GUESS they would have had to remove 
 part of the male spadix BEFORE it opened, as the female flowers are 'ready'
 at least a day or two before the pollen is produced, so Donna, do you have
 any idea exactly how they manage to 'collect' the immature pollen and
 'ripen' it??
