Crinum asiaticum germination

I usually end up harvesting the large asiaticum seeds after they have been 
on the ground, baking for a few weeks (not on purpose, just a scheduling 
problem).  A few seeds will have germinated on their own after a couple of 
months.  Generally, I bury half to 3/4s of each seed so there is a good bit 
of the top showing and then put the pots in partial shade so they probably 
get no more than one or two hours of direct sun each day.  Success rates are 
generally very good, but I also notice that some germinate fairly quickly 
and others from the same plant are quite delayed.  In general, I think that 
partially burying the seeds speeds germination up a bit but I haven't 
rigorously tested this.

Have you noticed more rapid germination if you harvest seeds directly from 
the pods vs after the pods have split?

I notice that many hymenocallis seeds often act the same for me.  I was 
loathe to bury them, since they are green and I assume their photosynthesis 
apparatus is working, however, I have fully buried seeds from the local 
hymenocallis that grows on the dunes and find it speeds germination and I 
get a 100% germination rate.  I have assumed that its due to reducing
