This argument has been going on in the daffodil world for years.  With 
respect to daffodils, the situation is just a little different.  As has been 
observed (in other submissions to the list) geophytes that set seed take longer to 
senesce but do so almost immediately the seed is ripe.  The daffodil stem is 
green and alive all through the seed ripening process and undoubtedly functions 
as a leaf photosynthesizing what the plant requires to keep it from drawing 
down the reserves in the bulb.  As a daffodil hybridizer, a given bulb in my 
patch will often carry a seed pod each season.  It doesn't seem to affect the bulb 
as it will bloom the next season seemingly without loss of vigor.  

I know of no particular experiements that have been done with daffodils and 
to examine this phenomenon.  It may be, on the other hand, that enough energy 
is drained (in spite of the photosynthetic contribution of the stem) from the 
bulb to preclude its dividing that year; I've never looked at the issue that 
closely to know for certain.  Bulb increase by division usually occurs each 
season under a normal growing situation.
